I wouldn't bother with body shops and take the doors to a metal shop. If they can't repair to as new they should be capable of fabricating a replacement.
The modern body shop does very little actual metal fabrication. Mangle a fender and they bolt on a replacement. Other body panels they will cut out the damage and weld in a replacement from a donor vehicle. Very little fabrication or shaping involved. The guys you can see on TV reworking a 32 Ford making new body parts are far and few between. About the same as finding a TV repairman who knows vacuum tubes.
