All I can say is GO FOR IT WITH ALL YOUR MIGHT!!!
Helicopter flying is one of the most satisfying careers there is. Imagine being paid for doing your hobby. I have been flying for 8 years and have NEVER looked back. I begged, borrowed and would have stolen if I had to in the persuit of flying helo's. I'm STILL paying for it, but hey, it's worth it, every step of the way.
There are some good schools in SA, so cruise the net and see what you can find. With the current Rand/Pound exchange, you are sure to save some boodle.
Good luck anyway
