Not sure if you're still reading after all the bickering, but the washing airplanes/lineman/airport bum deal is actually not all that bad. Ok, sure, it probably wont even cover the hourly rate for instruction but as you talk to the owners of the planes you get opportunities thrown your way. Business trips, ferry flights, airshows, etc always come up and if you're available and not annoying you'll most likely get those offered to you.
If washing planes isn't your thing, as previously mentioned, taking out a loan isn't a bad deal so long as you don't lose focus. Sallie Mae provides up to 100k (last time I checked) for approved pt 141 schools.
