Seeking small lot for construction of eco vacation house.

I live and work in the Los Angeles area, but am also interested in Florida, Wyoming, Washington, and Oregon - either urban or rural. Preferably flat enough land to build a low-cost, low-impact environmentally friendly vacation house. Depending on arrangement - I'm willing to provide branding, marketing, business strategy services - or - build a equal structure on the property for you as well. Ask for more details.
