Did you take the vehicle to the dealer, ask if they are an approved insurance repair facility. If not, get a quote anyway, then present that to your insurance company as the cost to repair.
Otherwise, it's always cheaper to go to an independent shop vs the dealership.
The problem is, the trim needs to be removed in order to get to the window. Some independent shops may break some of the plastic tabs that hold the trim in place. If one or two break, there is still enough to hold the trim in place that you wouldn't notice. Of course, the dealership may do the same thing.
The safest bet would be to sit there and watch them do it. Of course, some shops have those "employees only beyond this point" for insurance reasons (and also so you don't see them when they mess up).
Whichever place you bring it to, ask them what they'll do if the plastic tabs break. They come in all kinds of shapes and sizes. Will they replace it if one breaks. When the work is done, make sure the trim is secure and check all the weather stripping around the window.
Good luck.
