My favorite long-haul shipper is Brook Ledge, Bob Hubbard is second. Most recent price reference I have is $1700 from OR to PA last fall on Brook Ledge. Have had Brook Ledge drivers go above and beyond taking care of a first-time-traveler who wasn't handling it well. Unless you see the horse off yourself, or have someone you know/hire to do it, assume that any pre-trip instruction and supplies will be ignored. So far that's been the case for me 100%.
