Naturelink. I don't know how much the flyer says. They are a Wonderboom ( Pretoria ) based company. Operate Chieftans C402 BE58 PC12 , a B200 or two. The charter side in RSA isn't very busy and i have heard rummers from a very good source that you sometimes wait for your money. Charter pays only 0.80 cents a km. Best is you go see them.
