just call up a courier company or get some quotes off the net. (tnt,startrek,toll to name a few and are more then capable of handling small pallets or skids cause im assuming the box will be on one.)
Get the sender to pack and secure the box down good. and get the weight and dimensions of the total box all packed up. Then just call up a courier company and book in a courier you can make an account with them or pay by credit card. make sure you advise the sender thats its been booked in an expect the courier soon. if booked before 3pm they can generally get there the same day or next day. Many times ive arrived to do a pickup and there like, i know nothing of it, or the item isnt ready, which is a big pain in the ass and a waste of my time. hope that helps
