You can make great things on a budget, but what you trade in for saving money you put in lots of time, and elbow grease. Like previously mentioned it's all in the prep, and if you do go a panel at a time. I say do plenty of research first. I've heard some good things about single stage fleet paint, good tractors and such, I'm not sure if it comes in flat however. The dollar Wal-Mart stuff is a good deal though, but I've seen good stuff and bad stuff with that.
