To start a company of one, you should first figure out the smallest version of your idea and then a way to make it happen quickly. Automation can happen later. Scale, if desired, can happen later. Infrastructure and process can happen later. Focus on where you can test the waters without a massive investment of time or money, and then pay attention to what happens when casual contacts turn into customers, even if it’s only a handful at first. Why did they buy? What motivated them to do so? How can I keep them happy? And most important: How can I help them succeed?
