Botswana is a good place to pick up work flying a C206 for a start then maybe an islander or caravan after a year or 2. There are other places as well, Tanzania and Namibia come to mind. You use to need 400 hours before getting a job in Namibia but don't know if this is still the case. Unfortunately you will need to go out there and knock on doors to get a job, if you send a cv over it will just go straight in the bin. Plenty of info in the African forum if you do a search, it's been covered many times and you should be able to find everything you need to know.
