How do you know how long something takes to manufacture? Contact contract manufacturers who specialize in the type of products you’re considering: http://www.thomasnet.com/. Call a related manufacturer (e.g., toilet bowls) if you need a referral to a related manufacturer you cannot find (e.g., toilet cleaning solutions). Still no luck? Google different synonyms for your product in combination with “organization” and “association” to contact the appropriate industry organizations.
