I worked at an FBO while I was in school, I did it while I was instructing, I did it while I was furloughed and I still do it a couple days a month to keep their insurance company happy in the event I get furloughed again. In the mean time the money is going in the savings account.

Easy job, great for networking and if you like being outside you're set. Most FBOs that have rental fleets also offer some sort of discount or once you get to know the instructors they might be willing to help out with some free dual.
