Like Artisan said, you should have your phone number or email (phone number would be better IMO) on the Home Page.
As far as the location for the number, near the top right IN the "green bar" with the link buttons would be a good location. Just to the right of the "ON LINE INQUIRY FORM" in white letters and a nice font.
Also, your "list" next to the picture looks good but the one that says "Guaranteed to Satisfaction" is worded a bit odd. Perhaps "Satisfaction Guaranteed" or "Guaranteed to Satisfy" would be better.
All in all, the site looks good.
