I came in January, had probably 80 pounds of school supplies for schools, condoms for poly clinic, and some baby clothes to donate. I didn't have a specific entity in mind, but distributed items around several villages on the mainland and Ambergris Caye. We came through customs at the border from Mexico (flew into Cancun, ADO overnite to Belize City). When asked by the customs agent to declare, I told her I had pencils, erasers, etc. and none of it was for sale and would be donating it all to the schools. She waved me through without even looking. Can't say that would happen with 200 pounds...how awesome of you! A good contact for you would be Linda Carter - at the school just north of the bridge in San Pedro. She can assist you with a plan and probably a letter.
