Don't know for sure but,
Try these guys. While I am quite sure they don't do it, they could probably give you a referal for a place "up the hill" that may...

With a name like that, he can't be all bad. Good luck. I went looking for driveline folks in your area and couldn't find any. I would think that any place that can balance a driveshaft should have a pretty good idea of how to tackle one of those pulleys.
Good luck,
Anthony
BTW: Let me know how it turns out. I may be in the same boat someday.
