Given the size of boxes I see in the post office I would check with them as a first option. I know Graniels' ship chairs and other furniture items that way, so a regular shaped box shouldn't be a problem. Their fees are by weight.
Otherwise contact Caribbean Shipping in Belize City (227-7396), they are the local agent for Hyde Shipping in Miami. They charge by weight up to a certain amount and then by volume.
