Where to hot tank a crossmember in San Diego? (Even LA if I have to)

[botsdots]

Not sure where else to put this, but it's probably only a suspension problem, so here it is...

I've driven my crossmember to no less than 5 places and called another 5. No one in San Diego County can Hot Tank this thing.

I'm looking for a place that can hot tank it, but I'm striking out. Here are the places I've tried:
Kenyon Machine
Wholesale Automotive Machine
Diesel System Services
Oceanside Truck Service
Action Cylinder Head Service
Rick's Machine Shop
Hi Performance Machining and Metals
Cylinder Head Services
Jacobs Engine Rebuilding
Motor Machine & Supply

So I'm putting my question out the best people for this stuff... where can I get my crossmember hot tanked? I'll even take places in LA as recommendations.
