Money: What I know from guys in Maun, and i'm calculating with this sum is that the amount of 400-500 US $ per month should do it until you get The Job (in my case living in a tent, living low, but being able to be where things happen). If I'm wrong somebody please correct me.
Travel: we all go from different places. For me the cheapest and fastest is Budapest-Cairo-Joburg-Maun (1000 euro's, 25 hours
)
Cheers
