I launched my company as a self-funded solo bootstrapper straight out of university. I took some love money, that I mostly didn't use, and bought half of those shares back at ~4x the original price a decade down the road. 2k USD per month is nothing to a large company. Forget about the per month part, just charge a flat 100k USD package with 2 or 3 payment milestones over a quarter or two. You can give away IP too. You don't really care, you're not going to build your end-game software product on top of a rushed prototype anyway. However, you have to meet with prospects (executives). Lots of them. It's tough to even get one call, but once you get there, the one question to ask is: what's your biggest problem? and then improvise. After many meetings, you will see patterns emerge, both in types of problems and potential solutions.
