If it were me, I'd just go with someone who is well known and ship the 1911 to him. I can't say enough about Karl Sokol of Chestnut Mountain Sports in W. Rutland, VT. He's done several revolvers for me, but he's also customized 3 1911's for my friend, and they are absolutely perfect.
There has been several articles on his work in Comban Handguns. Along with many friends and competitors that I've known that have had work done by him, everyone from SWAT team members, DC cops, SEAL team members (VERY nice S&W M625) and people from all around the world. Instead of having someone local you really don't know much about do the work, I would highly recommend having Karl do it. I can guarantee you won't find a single flaw in his work.
I don't have his number right here, but if you call information for W. Rutland, VT, they can give it to you.
Hope this helps.
