Sounds like you are trying to get insights as to what business to start. I can help you find clarity and hone in on your goals and best possible target market. I have helped others in the past and can definitely help you find a product offering that you are good at and passionate about and help get you started on your right target market.

One short answer. Selling private labelled or even better, directly manufactured products via the Amazon FBA (Fulfilled By Amazon) program. This venture would meet all your criteria.

Web hosting, look at the rise and falls of the various hosting companies and after it all they are still new hosting companies popping up.

Hosting will always be in demand because you always have people who don't want to deal with the learning curve or tech.

I know what you are thinking, the web host market is saturated and you are right, godaddy, name.com, siteground.com etc...

But if there is competition there is demand, so how do you stand out? Simple carve out a niche and focus your entire offering around that niche.

Example: getflywheel.com - They are carving out a niche for themselves by focusing on agencies.
