The driver I use does not typically deliver buildings across state lines.
I can deliver buildings that are 8' wide and up to 18' long myself and I am willing to go out of state (usually).
If you take delivery out of state sales tax does not apply. You can use that fact to find your own driver (must be a professional) to come up (or down) and pick up the building. I may be able to work with you some on price if this is your circumstance. I will want to talk to your driver to verify they can transport the load safely.
