Jim is a good guy, and does good work. he's been around the suspension world for a long time now.
I've had him help with track side setup and been happy with the results I got from him. I have also raced bikes with his handy work on the suspension. Bikes felt good and the suspension performed well.
Have you called his shop to find out what's going on? have the responded to you? Don't send emails, CALL. Talk to someone and have them give you an answer. I am sure you will get better results by talking to them then asking around about their service (as I have never heard a bad thing about Jim and his business).
Good luck.
