For that kind of money, I would seriously consider buying the equipment you need and some old junk cars for a couple hundred bucks to practice on. You could even recoup the money you spent on the tools by doing some paint jobs on the side.

Serious. A garage paint booth is not that hard to build and after a couple of practice cars you can get pretty decent. A good paint job on a car isn't about the paint. It's about the prep work.
Painting a car is 90% body prep, 10% painting.
Search several classic car forums, most have at least 1 or 2 guys who have built the full garage paint booth. And there are several places that sell the tools/equipment online as well.
