Depends how involved you want the color swap to be.
Don't want the door jams painted or anything like that? I bet Maaco could do it for a grand but it probably won't hold up like OEM paint.
If you're looking for a complete color swap, jammed, engine bay, and pretty much everything minus the floor pans I'd say you're easily looking at 3-4k. The majority of that price would be disassembling and re-assembling the car. Since the car is fairly new, I'd suggest what someone else already said, get a different car the color you want. Since the car you have is practically new., you don't want it to depreciate anymore than it already has with a half-assed paint job.
Just my $.02
