Green Media List Website Needs a Logo!

This is the logo for a new web site and product that will be launching next month. I want something that is eye-catching and professional (especially since the product name is so routine)

Green Media List

Tagline:
Part of the Green for Good Network

Desired Color Scheme:
Green - similar shades found on beta.greenforgood.com

Desired Style:
Contemporary, professional, trustworthy

The site is similar to http://www.giftmedialist.com as well as a much smaller version of http://www.mediamap.com. GreenMediaList.com is going to sell a database of key media contacts who cover "Green" and/or environmental issues for newspapers, magazines, etc.

This site/company is tied to another Green company I run, GreenforGood. It would be interesting if we can try to tie in the existing logo for GreenforGood.com (http://www.beta.greenforgood.com) or something similar into this new logo.

PR and marketing professionals purchase these types of directories because it saves them time from conducting the research and allows them to contact reporters directly if they have a Green product or service for which they want to receive media coverage.
