KG -The LBS is your best bet. They would know where most of the local frame builders are located and even have a few recommendations to their favorites. Even if you have to travel a bit IMO it better to work directly with the builder as they can get a more accurate fit and see you on your current set-up. Even if there aren't any builders in the area, many LBS's are an authorized dealer for custom frames of a handful of builders. It usuallly means that they have been trained by the manufacturer to their fit standards or are at least familiar with the frame-buildier's fit guidelines(Is it just me or does every place do theirs just a wee bit differently?
) In that case, the LBS should offer to do all the tweaking that come with the purchase of a new bike and even change out parts(different size crank, longer stem, etc.) if need be. But definitely ask what support the LBS offers if you go that route.
