Please correct me if I'm wrong as I do not want to post misleading information for looser, but from what I have found, Kenya sounds like a good place to start. Seems like most of the a/c in country are either two crew (good for a co-pilot position) or in a category that a low timer would be qualified.
As for a source of information, you should really try and get your hands on a copy of JP Airline-Fleets. The best $100 I ever spend. Has tons of info on tons of companies. Trust me, if you have never seen one, take my word for it, buy it, you can thank me later.
Hope it helps!! All the best.
P.S Do you have any float experience?
