earthen plaster application

I live in the greater Sacramento area and I've recently learned about straw bales and earthen plasters. I'm completely in love with the beautiful simplicity of using the earth right beneath our feet to construct our dwellings and I'm looking for a community of people to promote this with. I searched for contractors with expertise and the picking is slim to nill from what I found. Is there not a market for this here, or is this one of the beautiful situations where the supply has not reached the demand?

If anyone from this area reads this and would like to start a small company in earthen plaster artistry, please contact me because I'd really like to brainstorm with you and possibly get something going.
