There are two ways to look at this paint thing: 1) Places like MAACO, and Earl Scheib do paint cheaply and that stuff tends to fall off easily. 2) A quality paint job (if you can find a shop that wants to do that kind of work) will cost some serious dollars. I personally have a lot of money in my paint job on my truck, but I also saved a lot by doing a large amount of the work myself. (sanding, prep, and buffing)
If you do the prep work and get the body clean and sanded, then there is NO ONE that puts as much paint on a vehicle in one day than MAACO or Earl. Those guys have experience in spraying paint. Do the dirty work and then pay them to spray it. Talk to them about how they mix their paint, because they may add to much hardener to get it to set up.

I don't know what brand of paint those guys use, but I am partial to a couple of quality brands and have some reservations about the others. I like the Sikkens and PPG are at the top end of my list with Dupont and Valspar falling in after that. Those others, such as R&M and Omni, are basically thinner with a color tint mixed in it. They are so thin, you pay for a lot of coats to get the coverage. Buy quality paint and do it right the first time.
One can almost paint a car themselves, if they want to do it right. It is not that complicated, once you set your garage up to keep the dang bugs out and wet the floors down.
