My coworker was backing out of his space, which is next to mine, and wasn't paying attention. This was a low-speed side-swipe kind of thing. Here's the result (forgive the grime, weather's pretty terrible right now):

Door does not close properly, although it will latch shut. I have not attempted the window. Mirror motor works fine.

I do intend to take it to a shop to get the work done. My questions to you are:
1) What kind of fix are we looking at here? Panel replacement? Door replacement? hammer/buff/paint?

2) Any gotchas I should be aware of?

3) (if you have an idea) general cash cost (non-insurance price)? I understand it will vary greatly, but I want to do what I can to avoid being gouged.

Thanks in advance for the help.

Oh, and any suggestions for shops in the Sacramento, CA area would be awesome.
