Liquid Protein?
Nope, I sure don't know anywhere to get them local. Kind of a bugger trying to get that stuff over here in germany. Did you think to ask someone in the states to get some and mail them to you. I am sure they could pack a whole mess of them into the Priority mail flat rate box for $8.95. Also starting March 3rd they are going to have a new larger flat rate box that can be shipped to APO's for a discounted price of $10.95. Maybe you could call one of the companies you are trying to order from and ask them nicely to put it in a flat rate box for you. All theycan say is No.
Good luck... Daisy
