It depends on how you want to do them. If you want them to open like barn doors then you will get it cheaper. If you want them to open the same way to the rear as they do to the front, then you are looking at much more.
make that decision and ask for pics of ones the shop has done. I mean pics of the doors open and closed, the hinges, bodywork throughout the process, bracing and all that.
This is right up there with boob jobs, dont skimp on a cheap one...
