Fork Repair Advice

I have a Marzocchi Marathon XC (air/oil one side, coil/oil on the other) which I trashed last night. I may have blown out some seal or valves in the air side, since it seems soft and the compression damping is totally gone -- when it happened I bottomed out hard and there was sound like a paper bag being popped.

Anyway, I was wondering if anyone knows what might be going on inside my fork, what may be needed to repair it, and most important: can anyone recommend a shop that can service my fork?

One Last Twist: Time is against me right now. I am heading down to Slatyfork next weekend, leaving Thursday night. I suppose I could rent while I'm down there but if I can get my bike functional in time that would be best.
