+1 for finding a local smith that could do it. Try to find one that does it himself so that you wont have to pay extra for out sourcing. In VA I had my local smith reblue a bunch of parts off my 1903A3 and it only cost me around $40. To save yourself some dough, take the old blue off yourself, any of the off the shelf blue removers will work. Cold blueing never turns out as well as you will like, especially if you want to reblue a barrel. Cold bluing wipes off easily, and doesnt leave a uniform finish. In the end you will be happier if you take it and get it hot blued, the finish is far more durable and looks a heck of a lot nicer. I tried Rebluing some of the parts for my 1903a3 myself and wasnt to happy with the end result. After I had them hot blued I was extremely pleased, they looked like brand new! As with any gun work, I would suggest checking the reputation of your local gunsmiths, see if you can see some of their finished work. A good gunsmith wont mind showing you their work before you let them at your guns.
Oh and to take the old blueing off, I used the Birchwood Casey blue/rust remover that the link posted goes to (they sell it at Walmart if you dont want to have to order it offline)
