Uhaul Truck is usually $20 a day and around .80 a mile, you could pick up a bunch!

If it's spray foam insulation, Acetone should break down the foam pretty easily. I'd go to harbor freight get an oscillating tool ($20ish) scrape as much as you can then use Acetone to clean up the rest.

But I bet you could pick up a stack, clean up a few for yourself, and sell the difference as is to cover all of your costs, plus.
