Gunsmithing Remington 700 gunsmiths in northern Illinois and southern Wisconsin?

Live in Chicago northern burbs. Looking to remove factory barrel to do remage conversion and would prefer ftf instead of shipping out. Thanks in advance.

If you’re not concerned with keeping the barrel in good working order, you can use a dremel or a hacksaw to cut a groove 1/8in in front of the recoil lug to relieve the pressure on the shoulder, then unscrew it by hand.
