I understand that you're looking for a blogger to do a couple of pieces a month on environmental issues, and I'd like to be considered. My work has appeared in dozens of publications including Vanity Fair and Skeptic, and I currently serve as a blogger for The Lazy Environmentalist in addition to a few articles on green subjects that I've done for other outlets.
I've pasted a couple of links below; please take a look and let me know if you'd like to discuss this further.
