Example:
90k daily Teen/Babe TGP with good production % sends 175k-180k to galleries, the rest to trades.
You could send all that to Free Hosted Galleries or your own galleries.
Average 5% click-thru ratio from galleries to sponsor tour (total 9k to sponsor)
Average 1:500 ratio for TGP traffic.
Equals 18 sales per day.
18 sales x $15 RevShare = $270/day
$270 x 30 = $8k/month
Not including hosting costs ($200/month for 1.2TByte), one-time cost of TGP script ($300) and traffic trading script ($600)
Either build that TGP yourself or hire a pro to do it for you:
