As for float operators in Africa, I'm sure there must be a few, but which ones, I have no idea. Actually, if anyone does know about float operators in Africa, I would like to know!!
Is it necessary, probably not as there must be far more wheeled a/c in Africa than float equiped a/c's. The only reason I asked was that I would have had a suggestion or two. They weren't in Africa, but, maybe you folks would have been interested?? Who knows!?? Usually folks looking for there first jobs don't really care where it is.
