I'm in about the same situation as you (except I don't have a commercial certificate, give me a month). Information about flying in those parts is hard to come by. All of the threads here are quite old and most recommend going to Botswana or Namibia and seeking out work in person.
Working in a foreign country is always a moving target. This month it might be India that needs pilots, quickly that turns south and now only Tanzania needs pilots, ad nauseam.
