"I noticed you're in the Bay Area. You might try going to Bicycle Outfitter in Los Altos and talking with them. They do both Calfee and Trek (since Dogmama brought up Lance) and they'd be able to tell you if you really needed to get a custom bike or if a production model would fit.
I have heard Sausalito Cyclery is also very good, but haven't done any business with them myself."
also try Robinson Wheelworks carries the Calfee, as well as Seven, Torelli, Mondonico and others. Chris Robinson and his crew are building my bike, built my last bike too. They do a lot of work for "mini cyclists" even pros, I'm 5'1". Good luck and enjoy the search!
