$180 is cheap to have a frame professionally painted. There is a whole lot that goes into it and the materials are expensive...I know I used to do custom motorcycles and did a few frames a couple years ago.
Look into powder coating it. It will last longer and be much more durable. I used the guy in Dawsonville. He did a good job on my cranks and the frames I have seen that he has done have looked great. You can find him on craigslist.
Everyone knows rusted screws on a bike means that you probably drove it underwater and that's bad a$$ in itself.
