Ouch! That sucks.
As MADDOG said, that is a very difficult spot. Unless you have some serious skills, I wouldn't even try to mess with it yourself. Take it to a dent repair shop - not a general body shop. These dent places are good at what they do.
I had a quarter sized dent in my driver's door right on the body line that runs with the handles - again, a tough spot to fix. Upon getting an estimate, the dent place noticed a 3 inch crease in the same door at the bottom that I never noticed before (like I said, these guys are good - dude looked at my car for 2 seconds and saw it. I had it for 2 years and never saw it.)
I ended up going to three places for quotes and they were all comparable. About $75-$100 for the quarter sized on the body line, and a bit less for the crease. I think I found a Groupon deal and saved some money, but ended up paying about $150 for both to be repaired. And now, you would never know they were ever there.
Can't hurt to get estimates. Just be sure to act surprised when they quote you and tell them that the shop down the street is much less - it's amazing how quick the price drops. Good luck. :fing02:
