Browse the threads on Maun Botswana. There is plenty of gen there on how to get a job in the swamps. That is one option, the other is to make a nuisance of yourself at the contract companies. If they are politically correct they will be more than happy to offer you a job due to the fact that you a female. That one is contraversial but a reality.
The guys in Maun work hard and play hard, and come away with good experience and many fond memories. Can't speak for the contract guys but it sounds interesting from the posts on this forum.
