Guides for Housekeeping/ Housecleaning Businesses to become environmentally friendly

We're collecting information about how to green your housecleaning business here. (We haven't started searching out information on how to start your own business, you'll have to find that on your own, at least for now.) Please contribute, post comments with new ideas.

Why is SpaceShare doing this?
Besides just helping other people start green businesses, we hope to have many green housecleaners join our "Little Green Expo," helping fund the rideshares to festivals by paying us when we find referals for you.

Below are ideas so far, add your comments:

Training and guides in the Bay Area:

WAGES. They are doing it, and teaching others how. General information, and training in Spanish in the Bay Area. From our limited experience, WAGES seem like a great organization, and we'd recommend them. Check out their guides early in your research, including replacements for toxic chemicals.

The whole story:

Nancy's Natural has a wide variety of thoughts and advice around starting your own natural cleaning service, written from her experience.

Information, especially for less toxic cleaning:

JP4 at Wester Regional Pollution Prevention Network Especially relevent for more instituional cleaning and for partial-conversions (they spend more time talking about what's the worst among existing cleaners, not necessary for someone making a full switch?) Includes links to EPA documents.
