I like the idea of using this niche to market your contracting services. However, I have one small nag. Building an MVP is not simply about cranking something out as quickly as possible. It's about not wasting time where it's not needed. But that means if your MVP proves successful, you better be ready to continue building it. And I'm guessing a lot of people won't want their MVP to be some 3-hour one-off built in PHP. I hope you have more than that to offer.
