Check on the references for the chosen delivery folks. When we bought our present boat down in Alameda, CA, we found a reliable trucker with some help from sailing friends.
Back in '95, the bid was over 2K, if we wanted the truck to move totally for our convenience, several hundred less if we could wait while they put together a schedule to coordinate with other customers... and half that if we could help them out by filling an empty back haul on short notice. (!)
We did just that, and the cost was around $1300.
The present costs will be adjusted up for inflation, but the requirements of trucking will likely stay constant.
Good communication with the trucker and flexibility in scheduling make a huge difference in the price.
If there is a reasonable price for the yard wrapping the spar with both carpet pieces and heavy plastic, pay it. Also PAD the dickens out of ALL rigging parts and any loose pieces stored inside. Any minute chafe, anywhere, will abraid glass and varnish. Duct Tape all hatches closed..... a thousand miles of a 60 MPH 'apparent wind' can open up places that seem secure. An experienced driver will help you, but do not expect him/her to spend much time at the load out point. Remember their creed: "If the wheels aren't turning you're not earning."
Take lots of pix; it's quite an adventure.
