To answer the OP's request, I'd suggest to become involved in a local EAA Chapter. SEVERAL offer flight scholarships. However, I'd also suggest he get involved in the chapter to become an integral part of it. If he shows up to obtain a scholarship, receives one, then disappears, that would be low.

I can't fault him for setting up his request on GoFundMe. It's the way things are done nowadays. HOWEVER, if he did any investigation into the demographics of the pilot population, he'd find that most are older and sometimes (not labelling all of us...) skeptical of social media/funding/guidance and therefore reluctant to participate. #1 rule for making a presentation is to know your audience.
