Have you looked into Scott Kunz aka TreeMonkey in Wisconsin. I know Its not exactly the location you are looking for but the man builds one heck of a saw no matter the brand. What are you wanting built, if you don't mind me asking?
I haven't, but I just did a quick search and found him. He's about a nine hour round trip from here. I could ship him a saw that needed complete re-build, but I'm looking for someone more local for little stuff that's beyond my know-how. In particular, at the moment I need a crank seal and chain brake replaced on a 660.
