Yep, Bilstien is in Poway, and the people that work there are SUPER helpful and friendly. I think it was $65 for basic rebuild.
I am going to rebuild one myslef here soon. It looks pretty striaght foward. I took the shock apart, and it looks like just: Dismantle the piston, clean and put on new valving, replace the seal on the piston... put it back together, add oil, charge with nitrogen.
I'll let you know how it goes.
