Just to give you an idea of cost...the AMD installation shop here in GA charges $700 to install a full quarter. So I'd say $1200-1500 sounds reasonable for what your looking at. Just make sure you ask to see some of their other work too before deciding If you've never dealt with them. they may turn out crappy quality. You never know.
I paid a total of $1500 labor for a full driver side quarter replacement, deck filler replacement, full trunk floor and both extensions replacement, passenger patch near rear, drivers new door jamb pillar, a dent in passenger door, and roof and trunk lid dents removed and stripped to bare metal and reprimed. All parts were AMD. So basically I had all exterior replaced or straightened from the front fenders back. But that was having a friends dad do it who is a retired body guy of 25+ years. He did take a little over a year to do it though. But mainly because he was having issues with his shoulder muscle and had to take it easy for a while.
