good luck with the sale man. 
+1 the key to cheap shipping is the business to business part . I can tell you from experience shipping to the same address but 1 being business and 1 being residential you can add roughly $75 to the total . If he slaps this on a pallet or something simiular shipping SHOULD be in the $100-$150 range ...... try R&L carriers or something like that , not ups or fed-ex they are out of their damn mind lol .
