As I stressed in How To Paint Your Car, the main part of making a paint job a sucess is the body prep (prior to paint) and the buffing and polishing (after the paint). So, if you can get the body straight and smooth, a shop such as Maaco or other similar shop can probably do a good job for you. You just need to talk to some of their past customers if at all possible, and explain to the shop foreman what you expect. If the foreman seems to understand what you are wanting, you can end up with a job well done. Like somone eqrlier mentioned, they can spray a few extra coats so that you have something to color sand and polish. If the foreman doesn't seem to understand what you are talking about, go elsewhere.
