Did a search for motorcycle shipping, and came across Uship.com. Had never heard of it but filled out the quick profile. Didn't think much of it, but started getting bids almost immediately - all sorts of different options and prices. Ended up choosing an option in the back of an empty van already on its way from Texas to California, that was faster and way cheaper than any commercial option. Not a scratch, and boy was it fast!
Use the feedback system to find an honest shipper. My experience was great!
