This $650K/Year Business Should Be Everywhere (But It’s Not)
Lake Taupo Hole in One ChallengeTourist Attraction $650,000 estimated annual revenue
A tourist attraction on Google Maps in New Zealand…
Lake Taupo Hole in One Challenge… Scenic spot where visitors aim at a floating golf target with a chance to win a hole-in-one prize.

What a brilliant business idea: they will pay you $10,000 if you get a hole in one on their 110-yard floating green…
An amateur golfer has a one in 12,000 chance of making a hole in one on a par three like this one, and this company has said that they pay out $10,000 every two weeks, which means they have 26 hole-in-ones every year…
But that one in 12,000 number is for an amateur golfer, not a casual golfer, which most of their customers are. I would bet it’s more like one in 20,000.
And if the average customer hits 20 balls for about 20 bucks, it means their topline revenue is about $650,000, and this place is making a net profit of $200,000 to $300,000 per year.
These should be all over America. All you need is a wooden kiosk, a floating tea, and some permission.
Why not start a business where math is on your side?

Glamhive StylistPersonal stylist $50 per hourSomeone sharing her experience hiring a personal stylist
The cost of the services was $2500, which included a complete closet review, personal stylebook, personal shopping, styling outfits of my existing clothes, and directions for future shopping…
she easily worked at least 50 hours between the zoom calls, designing, and shopping over the course of 10 weeks….
She earned every cent!
Sounds like it was all done remotely; no in-person shopping trips or anything.

Consider listing yourself as a stylist on there if you’re big into fashion.
Like any marketplace, it will take a while to build up a reputation and a good income, but clearly there’s demand for this kind of service

Tom has a plumbing background, picked up various online marketing skills over the years, started helping out other businesses via Upwork.

Google’s 601 AI Use Cases = Business Idea Gold Mine
Google published this list a few weeks ago
Interesting to see what the big boys are doing, many opportunities to do similar on a smaller scale or for a different niche 
For example…
Contraktor developed a project to analyze contracts with AI. As a result, the company achieved a reduction of up to 75% in the time taken to analyze and review a contract, with the possibility of both reading and extracting relevant data from the documents.
How about vibe coding a “contract summary” service for local freelancers or small landlords 
Clients upload their agreement (e.g. lease, NDA, service contract), you run it through an LLM fine-tuned for legal language, then deliver a one-page summary of the key dates, obligations, and risks.
You could even do this manually at first to test demand

Turned His Manual Service into a $4000/Month SaaS$1000\Month Side Hustle From Your Kitchen Table
Weary_Bird_1773Remote Online Notary $1000 monthly revenue
Mike R writes…
Of all the side hustles you could ink into your calendar, becoming a Remote Online Notary (RON) might be one of the most underrated. It’s low-cost, high-trust, and surprisingly flexible — as long as you’re okay learning a little legal lingo and don’t mind turning your webcam into a digital witness stand.
I chatted with u/Weary_Bird_1773 on Reddit, how a first-time notary got up and running for about $500 and made just under $1,000 in their first month — working about 40 hours a month. That included remote notarizations, mobile appointments, and loan signings.
It’s not flashy. It’s not passive. But it’s steady, real, and you get to help people in major life moments — wills, closings, medical directives — all from your kitchen table…
if you ever wanted a business that literally pays you to stay at home and stay on top of paperwork?
This might just be your stamp of destiny.
Mike goes on to explain how to find your first clients and scale to $5000/month
Father & Son Earning $50K/Month Within a Year Doing This
Steven ForrestCo-founder of Bull Island Breaks $50,000 monthly revenue From a recent article…
When Madden Forrest, 12, and his dad, Steven Forrest, 35, started breaking cards — purchasing and opening the sealed products to reveal their contents — it was just for fun. Pokémon cards were first, followed by football. Then Madden watched TikTok creators who livestreamed the process and sold cards to interested buyers.
Madden asked his dad if they could try it themselves, and in October of 2024, the side hustle was born.
Amazingly, they’ve already profited $70,000 in 2025 doing this, and reported $49,000 revenue in May (~39% profit margin) 
Which is even more surprising given that TikTok appears to be their main channel – with Steven presenting all the videos – and they only have ~7.5K followers on there 
And it’s not like this was an original idea…
We didn’t know what we were doing. We saw other people doing it.

Charging $1000’s Per Month Per Client For This AI Service
A recent video from Authority Hacker
The service
B2B cold email outreach as a way to generate sales for a client.
This is a wildly popular service which a lot of people are offering and a lot of people are paying for right now
They show one company charging between $2000 and $7200 per month for one campaign
Why is this so powerful right now?
AI lets you personalize every message you send so it feels to the recipient (if you do it correctly) that they’re getting a personal email… versus all the templated crap that everyone gets bombarded with every day.
So AI gives you the opportunity to stand out from everyone else who’s doing this.
They go on to break down exactly how to build and scale this service, based on their experience doing it for a client

Earning a Living From His Local Newsletters in Only 2 Years
Michael MacLeod is a journalist and the founder of The Edinburgh Minute, a simple ad-free daily newsletter 
He shares in a recent interview…
It started as a hobby in 2023, with the aim of making it easier for readers to discover local news while supporting local publishers and journalists.
Now, thanks to generous readers and a ‘pay if you want’ model, the newsletters have become my job. This allowed me to start a second one covering my original hometown of London last year.
Asked why local newsletters are so popular…
Newsletters remain popular because the rest of the internet is so toxic. Our inboxes are one of the last-remaining safe-ish spaces on the internet. Readers tell me that some news websites are so bad, they’d given up on trying to follow local news.
I’m bullish on the idea that every city/region can support a high-quality local newsletter

The business: mailbox installation and repair 
Chris references a 2-year-old comment on Reddit…
I did an entire neighborhood last year. I fixed, straightened and painted a total of 23 mailbox stands. I charged $9k. I had it done in about a week. I had to replace 2 stands completely that held 6 mailboxes too. You can make really good money.
$9K for 23 mailboxes sounded excessive to me at first but not by Chris’ math…
Let’s say you live in a city with 100,000 people. Standard mailboxes need replacement about every 10 years. That means 5,000 mailboxes in your area need work every year.
If you capture just 5% of that market at $500 per job, that’s $125,000 in revenue…
There’s a massive opportunity here that almost no one is talking about.
