If you're getting a shop to paint the car, have them do the prep work. Most shops will frown upon getting a car in that is already prepped and will blame any blemishes and failures on the person who did the prep.
If you really want to go through with this then start researching. You'll need about $100 in sand paper and alot of time. If there are body spots that need repair the price will only go up from there.
