Already have, Ian.
I advertise right on the front of my home page that I offer green cleaning, and hypo allergenic cleaning. I have had only a couple of responses, and only those who are sensitive to the chemicals. My opinion is that most people who are "green" do their own cleaning, and are not willing to pay to have it done professionally. But, as mainstream media plants the bug into "Holly homemakers" ear, we will see a much stronger pull to the green side. There is a market out there already, as evidenced by a company here called "Zero-Rez", and another called "Ecofresh." These companies charge much higher prices and cannot produce the results I am able to do with my regular non-green cleaners. In the end, results and price are all that matter to consumers. We are at the mercy of the chemical manufacturers to produce products that actually work while still being green.
