Okay - I thought the title would get you looking
Serious post though - help needed.
The consignment is - to put it non-technically - "grass cuttings". Nothing illegal or that can be smoked(!) but a simple commercial shipment of lawn-grass sprigs from Antigua to Riyadh.
Volume around 550 cubic metres, but preferably shipped in two loads. Weight? - probably about 400 tonnes for the total amount.
Shipping conditions? - In bags, and on pallets, and needs to be kept "chilled" (like fresh vegetables) but NOT frozen. Should not be "in transit" (or any other kind of van

) for more than a couple of days or so..
So my questions:-
1) What sort of aircraft (if any) would be suitable as a full-load charter?
2) If feasible, who should I be talking to? If not, alternate suggestions as to air freight options?
Yes, I know I have strayed from my R&N and Jet Blast, but hopefully the Freight Dogs can advise beter than my usual forums (fora)
