Hello,
Instead of selling your good PR websites, may I suggest a few alternatives?
1. I can send traffic to your website regularly from US and EU, which are 100% Google Panda, Penguin & Hummingbird safe. This will give more value to your site on the market and will fetch you a higher price. Sell it once you have good visitor base and higher Alexa rankings.
2. I can send traffic to your site and you can monetize using ad networks. If you have more traffic, it is easy to get sign up with high paying ad networks. I can help you monetize as well.
Let me know if any of the above suggestions are interesting than selling your sites at this point with low traffic.
Thanks
