I am looking to buy reviews and/or links on quality websites* related to renewable energy/biofuels/solar energy. PR must be equal or higher than 3.
Please PM me with your URLs and prices. I will not respond to those without a price. Reasonable pricing please.
* A quality website is a website which contains ONLY unique and original content, which has been indexed in Google (the older the better) and which doesn't have more than 10% sponsored posts. It mustn't be built on a dropped domain!
