Most freight companies "prefer" a commerical address, with a loading dock. They will charge you a "convience" charge if you don't
Yellow and Roadway, are now the same company so they are not going to be very competitive on price.
Con-way can be expensive, but they are usually faster than anyone except air freight. They will require a way to unload the motor at the destination.
Overnite is very cheap, but they are just about the worst piece of crap there is. They are really nothing more than a tax write-off for the Union Pacific Railroad.
Fed-Ex freight, is pretty good. The are Viking or Fed-ex West in Washington, and American or Fed-ex East in Ohio.
Put it on a pallet, everybody charges extra for any freight a guy has to get off the forklift to handle.
Most everybody, will charge extra for lift-gate service. But at least the motor is on the ground then.
