Does anyone have any experience of premium rate phone lines and the associated costs of running such a service at all? I've done a bit of research and come to phonepayplus which seems (I think) to be some kind of regulatory body, but it doesn't seem clear just how much it would cost to sign up and have a number of different premium rate numbers. Is it hard to set up, and what kinds of costs are typical. Any help would be greatly appreciated. Thanks.
