HI Mars,
It doesn't say where you're from on your signature, but, I use Clean Racing out here in So Cal. Steve Searcy is the owner, and he does great work. If you're out of state that's not a problem as he does stuff from all around the country.
I would suggest however that if you are going to re-valve your shock you will need to make adjustments to the front as well. In fact, depending on your weight, you might need springs as well. It is definitely worth the money.
If you need Steve's contact info, let me know.
