if you're only paying $5000 for body and paint, you can expect to need another paint job in about 2 years. I'd be shocked if a legit. shop could do minimal rust repair, get the car straight, and paint it for under 20k, to do a fair job. The shop I work at, if car came to me with all metal work done, i would get all the door gaps, etc correct and flush, fit all the trim, do body and paint, sand, buff, assemble the body; it's a minimum of 35k. a good show quality paint job can be figured at 1,000 hours of labor. To do a good, quality job without the paint falling off in a year for a "driver" id still guess around 500 hours.
