Try Luthermusic, about 40-80 for bridge refitting and setup, depending if you need to buy a new bridge. I sent my vintage Yamaha FG150 there, a lower end model in the first place, and it came back pretty cool~
If your in the west you could try Seekz or Mike. Sound Alchemy or Standard Value respectively. In the east, Beez is the man to see! Look for Beez~.
