Belize Ministry of Health has been attempting to establish a medical tourism business, you can speak with them and see what they require. The major hurdle for the stall in services has been that Ministry wants foreign investors to send foreign patients and use Belizean doctors. Not what US, Canadian and Brit docs want to do as it takes away their income. There is a compromise but not sure if people will reach an agreement.
I will say that you need to visit prior to actually considering, seems like you are doing surgery before the labs are back... Doc.
