There are a number of shops in the Concord area, and I'd check around to see if one of the others is more Campy literate, and maybe has more of a fix, rather than replace mentality.

In any case, before you spend anything, set an absolute cap on how much you'll put into this. Replacing a component or two, especially wearing stuff like a chain or cassette may make sense, but if it needs lots of new stuff, the cost may go beyond what it would be worth. Bikes continue to improve, and you can go new with comparable quality for not much more than a repair would be if you need too many new parts. The other advantage of a new bike is that it resets the clock on obsolescence which can become very important another year or two down the road.
