Assistance for International Business Planning
"If you own a small business and are considering exporting U.S. products or services, a great place to start is the BUYUSA.GOV web site for the U.S. Commercial Service of the United States Department of Commerce. The U.S. Commercial Service helps U.S. companies find new international business partners in worldwide markets. Additionally, the service helps companies outside of the U.S to find U.S. suppliers of products and services. A database of offices is maintained on the web site as well."
