Hey Checkout IMlive (pussycash see sig below)
I'll try my best to answer your Q's
1 & 2 ) if the surfer pays for a minimum $25 chat credit then you get paid for a sign up. The current payment is $50 and you could raise that to $100 if you work really hard. You could opt for the $1 free email verification sign up. If you have crappy traffic this is ok. But really the pay per signups is were the moneys at.
3) Tons of Build your own banner/gallery tools with pics of the specific host you want to push. Whatever fits your traffic demographic. However Letting the surfer choose may be more money making in the end. They are certainly sure to find someone hot LIVE immediately.
4) the question you didn't ask was "Can I win a Porsche?" with Pussycash & Imlive the answer is
YES.
