should be easy to get many online quotes (although if it wont drive itself on the trailer it can be more difficult)

cant see how anyone could do it for you cheaper than a transport company really

for someone like me who has a trailer it would take all up prob 18-20hrs, plus fuel, would be easy $100/hr, so your talking a couple of grand, in fact add in a second person to take some shifts driving, they need a cut too, so $2500+

chances someone is driving that way and happens to have an empty trailer - none - unless they are in the business of moving that sort of stuff

bite the bullet, you either DIY to cut the labour cost or pay the cash so you can stay at home and wait
