CJ PayPerCall

Is anyone actually making a substantial amount of money with this? If so what are the providers that are giving you the best success? Was using the Art Institute and Wysong made about $60 but thats it..Was just curious to know if anyone else is making some good change off this...

I've made 0 with it so far. Haven't found the right method yet...so $60 sounds great to me, but I know there's more potential.
