Freight shipping for books to Malaysia

Good morning. My organization, Educational Tools Galore Foundation, is in need of some shipping information please. We are trying to ship some educational materials to Malaysia and want to find the most cost effective way to do so. We are based out of Hartford, Connecticut on the East Coast of the United States and will be shipping to our distributor in Kuala Lumpur, Malaysia. We have about fifteen dozen pallets to be shipped over there so the load is quite significant. The shipment is primarily books, but there are some magazines and other educational materials in there like flash cards and DVDs to round out the learning experience. The materials are geared towards elementary school aged children, if that makes any difference. We are a non profit organization so, again, we are looking for the most cost effective way to do this. That being said, we would like to find a reputable company to work with and not some fly by night operation.
