If not I'm out of suggestions, I'm afraid.
As for the other.. is going down there a possibility? If not maybe post them a copy of the work, recorded delivery, so that it'll have the date on the postmark, proving when you sent it.
That way if you can't get in touch in time at least you'll be able to prove the stuff was 'handed in'.
