I like the concept of your site, where a business can use it as a listing in a directory and then use that as their own business webpage. I think the name of your site lends itself to that concept well, too.

One thing I noticed when I went to the homepage is that it is slightly confusing for the visitor, because it's hard to grasp the concept of the site when the homepage has links for vendors interspersed with links for directory browsers. It may be to your advantage to clearly discern (visually) the links for vendors versus directory browsers.
