Rich Lee, looking at Spaced posts, it would appear that he may be a student looking to make his mark on an already crowded industry. I would suggest that those with low hours get an endorsement on a type that is commonly used in the low hour areas of employment, usually tourism, ie R44, or B206. In Australia I don't know of any 500's used in such ops.
I'm with fatter bloke, your money could be better spent, although the 500 is great to fly.
