If not glider tugging, how about parachute flying ?
Even parachutists are a bit picky about who gets them aloft, but you may find more opportunities here, depending how far you're prepared to travel.
Or you could get yourself a single seat PFA machine and rattle off some real flying hours and see the country quite cheaply. (and learn a lot)
I can think of one such person who bought a D31 Turbulent and flew every flyable day until he got the magic 700 hours that he needed.
