I used to be in the same situation. Two pieces of advice come to mind from my experience. 1) If you have a problem, most likely someone else does too. 2) Although others can replicate what you have built (proves it is a good market fit), many will still prefer to pay something reasonable for it (to save time or simply because they can't build it on their own). Just make a landing page for a handful of "projects" you already built, post on HN/twitter, and see how much traction they get (google will also pick them up if it's a good niche). At that point, you will know if investing time for minimal packaging (payment system, user admin etc) is worth it.
