Derrick at Horizon Customs in College Station is putting out some good stuff.
I'll second that. I haven't had a rifle built by him, but I have several friends that are more than happy. He'll probably get my 6.5 Creedmoor or 6.5X47 build.
Chad Stanley with Titan Firearms in Fort Worth, TX also does good work. He's built for me and multiple for friends using 700 actions that have been hammers.
Not sure if McWhorter will take your action and do a build, but every McWhorter I've owned has been A++
