I spoke with Jeff not too long ago...he's basically a one-man operation...I remember he does quite a bit of ice racing, so maybe he's prepping for that?
I'm sure any of your local suspension guys could probably do a decent job on it...I would maybe try to ask any riding buddies for local recommendations or search on Facebook for local riding groups and ask them...otherwise, you could send it to a major builder like Enzo, etc and have them do it.
