I used Auto Driveaway to get my ex's Golf from Washington State to Maine.  I
don't remember the cost but they got the job done.  I had to drop the car off
at their office  and it took a while for them to find a driver willing to go
over the Rockies in January.  From bad memory it took about 5 weeks to get the
car to Maine.
Good luck!
