I painted my truck myself but I also worked at a body shop for a few summer so I at least had seen what to do.

I did it in a garage with fans for ventiltion.

Overspray will happen, Prep is a crazy bitch and I hate bondo. Plus it's been 5 months since I did it and I still haven't wet sanded it.

The whole Maaco or something like it is crappy is all about prep. You'd be better off spending 20 bucks on sand paper and scuffing your own car and maybe removing some trim pieces yourself and then going to Maaco than you would most likely painting it yourself for the first time.

Plus you should find friends who've got a compressor and a gun and then you could jus tbuy paint locally.

good luck
