Hi,
AWE, the program of
LiveJasmin and many other sites is a great sponsor to start with
They have 4 packages for members, $29.99, $59.99, $79.99, $99.99. Users often start with the $29.99 one but after a couple of days they go for the higher priced ones. Very sexy models there... and even porn stars (who can charge more than 5 credits / min).
AWE is a very reliable sponsor!
