Here's a few to try:
Sim Daley - has a website I think its
www.simdaley.com - he's a great builder/repair guy. I would be willing to bet he can do the work on classicals too although he mainly works on steel strings and mandolins. He has a fantastic reputation around Nashville.
Jim Grainger -
www.customfret.com - in Sparta, TN. Great repair/retail shop. Good people too. They'll tell you if they can't do it.
Gruhn Guitars - big time high end stuff in Nashville but they do good repairwork. I'm sure they could refer you to a classical luthier if they can't do it.
