What part of the state are you in?
Up in the Shreveport/ Bossier area, there are a few.
Willis out on 527 does good work (or at least that is what I've been told).
DavTech (Swan Lake Rd) has a gunsmith on staff as well.
I have had personal dealings with DavTech, they took care of my issue quickly, but their customer service left a lot to be desired. I talked to a smith at Willis' and he seemed knowledgeable and had no trouble talking for 15 minutes about pretty much nothing, several people that I work with have had work done at Willis as well.
As was mentioned above, Clark's Custom Guns in Haughton/ Princeton (Shooter's Ln) also does good work, though I think they're limited on what they'll work on.
good luck
