It's no myth.
I know of two places where hoursbuilding is available.
Try
Commander Chuck who flies a JetRanger out of Fullerton Airport which is not far from Disneyland / Notts Berry Farm.
There is another place at Van Nuys. I can't remember the name, but I'm sure someone will know.
Both cover the same area.
I flew with Chuck a few years ago. The cost then was $100 per hour.
A word of caution.
Some people say the CAA will not allow the hours towards a licence/rating because you fly from the right seat. I didn't research the point because I did it to build experience, not hours.
I don't know whether this is true or a myth. It sounds absurd, but that doesn't mean ........ etc etc
