Know of any competent gunsmith who does AR 10 barrel chambering? I have a blank barrel that needs the following: thread barrel and fit extension, drill/ream gas port, cut to length, crown?

Any help with website, phone number, name of gunsmith who is known to do AR 10 barrel work would be greatly appreciated. Thanks!
