Barrel threading

[mc762x54R]

I have a bolt rifle barrel I'd like to get threaded.
I know Ahlmans does it, any other recommendations?
Has anyone had this done at Ahlmans?
It's about 0.86" at the muzzle, I want 5/8×24 threads.

I've had several done at Ahlmans. The work was solid minus I was told a price would be about 150 bucks less and that they would be completed before a trip I was planning on taking a couple of them on.
If you don't live near them I would bet the other companies listed last time someone asked (may have been me) would be a better option. If Ahlmans wasn't busy and I wanted to go for a drive I'd go back.
