Body work is probably the biggest pain in the ass car work there is. It's hard to realize how much work it is till you have to do it yourself. You'd have to do some pretty big favors to get anything cheap even for side work. When I had my beater repainted I had a friend who used to do bodywork for a living help out, and we put probably 30 hours or so into bodywork on a car that already had a pretty damn straight body. To get just a rear 1/4 panel done bodywork and paint wise you're probably looking at about 15 hours of work for that single panel.
