Chaps, just be aware that many helicopter positions are filled by ex-military guys who have lots of heavy or turbine time. It is a VERY long road for a young guy to start a CPLH on his own dime and make it in the industry. With MoD cutbacks the market will constantly get flooded with well qualified, tried and tested pilots.
My advice would be to look long and hard at your prospects before dropping 50K on training with very little chance of any type of employment at the end.
Remember also that many of those ex-mil guys who are now flying heavies for airlines also freelance as chopper drivers, which kills the market even further.
Its tough out there, and it won't get much better in the Helo game.
