There's a slice of the market around the world that charges $15 - $20 an hour and is just as ambitious as you are. In 20 - 30 hours of work, you can build a pretty decent MVP that is enough to test out your idea.
20-30 hours - does this include a Unit test framework, a code review process, QC front end testing, security considerations, documentation? Probably not. Again you get what you pay for.
if you cut too many corners, you will have a circle and it will eventually come back on you, which you will pay for your decisions.
