Be wary of services that say they will help you get on reality TV. Theres no need to sign up for such a service when the networks frequently post advertisements for the shows they are casting. The network websites will provide information like what the show is about, the kind of candidates they are looking for, and when and how to apply.
Here are some examples of network casting pages. (If these pages have changed, go to the homepage of the network websites and look for the new casting link.)
