IMHO, a type of business that would be successful in Belize is a service-type business, like plumbing, electrician, A/C repair, computer repair, house-sitting, etc. etc. In know that Belizeans already fill many of the niches, but the beauty of a service business is not having a bunch of inventory, and if you already own all your own tools, not much overhead.

FYI if you are thinking of importing blank t-shirts for printing/selling you will need an import license from the government for each shipment. The license usually only lasts 30 days, sometimes 45 and at times that will only approve a reduced amount. Strange but true!
