Forward Air is a "cheaper" (prices) shipping company.
http://www.forwardair.com/ I have never used them, but I know others on here have. Not sure, but you might be able to use Greyhound bus service. I sent a big 4x3x4 Gulf Oil cabinet from Texas via greyhound for a cost of like $40. Everyone else (FedEx, UPS) wanted like $150 to sip it.
