p><strong>I think your first step would be to <a href="/companies/" target="_blank">search the Ecohome Building Directory to find green home building contractors</a>.</strong>  You can search by region and by trade, so hopefully there may be some local experienced green builders in your area that may want to be part of your research project. And if you aren’t able to find any right now be sure to check back regularly as new companies are added every day. Also, I would keep an eye on this thread, with luck some siding installers will see it and perhaps reach out. This is about the only way we can help you, any contacts we would have would be in the listing pages.</p> <p>Good luck with your project, and please feel free to stay in touch with us as you progress, and if you have any stats to share with us and our readers that you think may be of value just pop them on this thread. </p
