How to get a car transported from Seattle to Tuscon

Hello - new lemoners here, we'd love to participate in the upcoming race near Tuscon though don't have enough time for the drive there and back.

Anyone with recommendations for cheap(?) transport companies or strategies for getting a car + a few things to Tuscon from Seattle?

I had hoped there might be an amtrack option, but that seems to be an east coast thing.

Thanks for your help :-)
