Yeah, good luck getting developers to work days on end to create a MVP for a founder at 200 or 450 bucks. My going development rate is 265 an hour. Also a MVP in 2 days is not likely or feasable, a demo with smoke and mirrors to show to vc or angels. MVP "Minimal Viable Product" means a working version ready for sale with the minimal set of features to make the product a reality.
My 2 cents is connect founders and Developers to make a match for long term projects, Match a CEO, CFO, and CTO. Work on building founder Teams, not trying to to match a wantrapanuer who doesn't value a Software engineers time and abilities is not willing to pay for that.
