Best way to ship 18' K across country?

Could someone please suggest a way to reasonably ship a kayak across country, from OR to WV? I don’t think the seller would be interested in trying to pack it. I found one company that does it, but it is very expensive. I heard that there may be someone who will do it for ~ $100.

Thanks so much!
