You would need to add more content, I think. As far as on site ads, I would recommend
Ero-Advertising. Traffic trading widgets from
Plugrush could be used instead of the current
Juicy Ads ads. Popunder from
Traffic Shop should be a very good way to go too.
If you consider a mobile version of your website, go with
Bitter Strawberry (they are very good, especially on high traffic sites), or
SexGoesMobile.com.
