I'll give you an idea. My Mum's Lancer had her back left bumper scraped. All that is showing is really the trucks white paint. This is a basic job to do. They do need to remove the bumper and respray it though. The 3 quotes were about $777, $788 and $980.
So your job will be anything up to $1000 or more. Try and find a small independant place that might look crap on the outside but on the inside might offer a lot cheaper prices. I did that once with my car. A guy charged me $500 instead of $1000 like other places.
