How much would it cost to paint my oxidized car?

I have black 95 honda civic and would like to get the entire car painted back to its original color (black). Unfortunately the roof and the roof of the trunk is severly oxidized. What should I expect to pay on average for a job like this? Its an older car and I'm not wanting a very expensive or elborate paint job. I simply want to spruce it up and make it look decent again. It's an outside car and is in decent condition. I'll probably keep this car for another 5-8 years. Any and all advice and recommendations would be greatly appreciated.
