You can get a C206 rating at the parys parachute club it will cost you roughly R4500 this includes the 1 hr flight time, technical and paperwork, you will have to pay an extra R3500/hr if you fly for more than 1 hour.
And the GA8 Airvan you can do in PE for roughly R5500 or R6000 not sure what that includes though. Its for Algoa flight centre.
Enjoy!!
