It's not a big deal to cold set a frame. I've attached a picture of my father in-law spreading my 1972 Paramount frame to 130 from 120 using a Swedish clamp. Worked like a charm. A frame shop will probably charge $50 or so to do it for you.
Concerning the brakes, I bought some used modern campy chorus brakes to put on my frame. All I had to do was drill one side of the frame out a little bit to accept the recessed brakes. Again, no big deal.
