I routinely ship live trout eggs in Styrofoam coolers via Fed Ex Express which is overnight delivery. I don't know how much it costs since it is usually paid by the recipient, but guess it is probably $60 to $80 which is what I've paid for overnighting live aquarium organisms from Florida. I would think you could get away with 2nd day delivery if packed with ice or dry ice. If you were shipping in the winter you could probably get away with less ice.The shipping coolers I get are from a company called RADVA base in Virginia and I think they sell various sized containers for your needs.
