In reply to Tobes:
A couple of weeks ago we had to pick up a similar amount 333 miles away, then bring it home. We drove in the end, but we did look at DHL delivery (which is cheaper depot to depot rather than door to door) before we went. DHL would have been much cheaper, but we decided we wanted to make the journey anyway, for fun, even though it cost more
Is it worth a look at DHL for you, maybe? Of course it depends on the stuff you have to shift
