You should take a look at http://www.GreenHomeCoach.com
They will provide you with a Builder Coach who is a licensed contractor, and one that specializes in green home construction, and you can save at least 20% on the cost of the home because you do it yourself. You will also get access to online project management software similar to what builders use when they are building a house, so that helps to make the entire process really easy.
If you want to build a green home , you should do some research on zero energy homes. With the money you save as an owner builder , you can upgrade to building systems required for a zero energy home, and in the end, you will pay roughtly the same cost for your zero energy home as a conventional home purchased from a builder.
