You're going to have to take it to shops and get quotes. You'll get costs anywhere from $2000 to $20,000 on here. Color change will cost more, do you want the door jambs, underhood done, etc? Is there any damage or rust that needs to be fixed? We couldn't even begin to give you a ballpark number. There's just too many variables we can't answer. Maaco could do it for like $1500. A real, good shop, doing everything properly, is going to be probably $20k. So, somewhere in between that.
Edit: I just saw your other post, yeah you got some damage that needs to be fixed too. You're going to be looking at more on the expensive side of things; big dents, scrapes, etc etc.
