What type of work do you need done?
There is a guy in Sandusky, Ohio that I used to shoot pins with. his name is Van and he runs a shop called Gunworks IIRC. I could probably find his contact info. If you're in need of someone to just help swap parts, I'm in Bowling Green and a fair hand at ruger single actions.
For better suggestions, you may want to try over on the ruger forums. I recall that one of the frequent posters there is a former dealer living in Chardon. He will have the good information that you want.
