On the main foot fetish sites ($6000.00) I also have available a TGP that was afake TGP I used to drive some traffic back in the day.
It only has galleries for this main site. So you have the gallery submit content, although you would want to do new galleries for the content, and you could use it yourself. Or just re-skin the TGP for your own purposes.
It runs on TGPX I believe. I am not longer using the TGP for anything since I no longer promote this pay site. That said, I checked my Google Analytics today and saw that this TGP also has some killer SERPS for relevant keywords.
I no longer need this TGP and you can take it along with the pay site. So you get even more tools for you to promote the site, and even more nice SERP results for your pleasure.
