Shipping advice, Maine to CA?

Hi everyone, I'm trying to figure out some inexpensive but reliable shipping from Maine to CA for an early 60s chevy truck bed. It's dissasembled but includes all of the sheetmetal. Needless to say, it's a large piece! Can anyone recommend a good shipper? We've got a quote at $500 but would like to do a lot better than that. Also, any advice on crating? Wish we could just pick it up, but it's too far away so we're going to have to trust to others to take care with the stuff. It's a very nice bed, practically NOS. Thanks!

 

try gray hound just bubble wrap it

 

Greyhound! I'll give them a call. Thanks!
