Being rich isn't everything and you have to be plenty rich to be bothered to fly circuts at the aeroclub or swan around in your R22 thinking you know what you are doing when you really don't...
Flying helo's privately is a slow way to waste money. Get a PPL (A) and drive something faster. What are you going to do with a helo in the UK anyway? Fishing in the mountains? Hunting?

As for making a living from Helicopters? First learn to drive one and operate it for 10yrs and then take that experience and reputation into a business. Maybe you might survive and make some coin. Goodluck.
