IMO, if he can't justify the 90 bucks, he does not believe in it, and will not be the right partner. Even in times when I was completely college-student broke, I could find ways to come up with $100 for the right opportunity. I'd also question his availability and opportunity to contribute if he will still be finishing studies for a couple of years. The first couple of years are arguably the hardest, and most formative part, of the whole operation.
