A pdr shop isn't going to touch that probably.
nissan is right when asking the question, whats the end result you're looking for? You've got extensive damage there, if you have a bodyshop do it you're looking at an area around $2k. Can you take me a picture of the inside (interior side) of the door? Its possible that the skin wont be enough and you're going to need an ENTIRE new door. Used parts can help defer the cost there. You also have the issue that if you notice the door jamb and the lower part of the rocker panel and damaged pretty badly, the metal is actually torn where the trim along the bottom connected to it. Thats going to need to be cut out, and new steel is going to have to be welded in there and ground down, prepped, and painted. Then the door will have to be painted, hung and aligned, the trim will be replaced and the paint will be matched.
There are two ways they can do it. A average shop will wind up painting probably most of the drivers side blending the color into the existing paint to match. A good and state of the art shop will buff the paint and use a optical sensor to match the color with a myriad of different possible shades, then paint only the panels effected (the door, the rear rocker, and the trim) and not blend. This will cost more.
My best guess is any bodyshop is going to quote you $2000. Since she hit you, isn't this her insurance? Why the worry over the cost? Let her pay to redo the whole truck...
