I do not live in your area and have no idea what or who is available. That said, have you tried posting on your local sites like Craigslist? If you use their discussion pages you may get some more relevant information. Otherwise you are likely only to get reputable service by shipping or travelling. I do not know if there is a Bose forum you could also ask on. There is the Tapeheads forum, various audio forums and USAudionart.com . Here in Canada we have something called Kijiji, in the US I beleive it is something like EBay trading or similar. I hope maybe these suggestions can help you. All the gear you listed is worth working on and worth waiting for the right tech to work with you. Best of luck to you in your search.
