Ruger Mini-14 barrel cut down and threaded

[SGTMAJMVJ]

I want to cut my Mini-14 barrel down to 16 1/2 inches and get it threaded. I live in Mableton and need a local gunsmith. I used the gunsmith at Adventure Outdoors to do this to another rifle years ago but I checked back with him and he can't thread barrels right now.
