What is the average cost to galvanize all the pieces on a Land Rover?


The places I've contacted are being a bit coy: they quote minimum prices to do stuff (150.oo) , but I can't get anyone to give me a rough estimate for a complete galvanizing job---Soooooo, has anyone had a load of parts done lately, and what was the cost?

Bonus question:
How is it calculated?

weight? square inches covered? amount of zinc used?
