I just shipped my 21 from Detroit to San Diego using
www.uship.com
I saw every thing from cats to lobster pots to airplanes listed.
Post what you need, shipping points and you can even set a target price. Truckers big and small start bidding on your shipment. You can read their feedback to get an impression. They might have room in a pickup or a box truck or a semi.
Certainly saved me a ton of time and money.
Good luck.
