I have a PR4, DMOZ, YAHOO, and Google listed site where I can sell links.

Niche is psychology/health. We have a few articles in English but the rest of them are NOT in English. However, if you are looking for PR increase, this is a great deal, no matter of the language. Many of the internal pages have high PR.

Your link can be posted in the sidebar, site wide or homepage only. You choose.

The price is $100/year. That's a great price for a PR4, DMOZ, YAHOO, and Google listed site.
