Looking for recommendations- Gunsmith for SBR project

Hello all, I'm looking for a gunsmith in middle Tennessee who can do machine work and some stock adjustment/woodworking on Class 3 items such as SBR and Silencers.

I've reached out a a few spots and it seems like shops either don't have the proper license or don't want to be bothered with paperwork for jobs involving Class 3.

Any recommendations would be appreciated - thanks.
