I was quoted $1000 or so US and that was for the outer skin only-welded and painted, when I was looking for a car. The panel is still in inventory. If there is damage to the inner panel that is another matter. A good Body Shop should have the picture above and the Mitchell estimating guide as well. ANY Honda Dealer can give you a printout of the picture and the parts list.
The repair will be better this way than trying to section it in.
