Integrated Directory Plugin

Hello,

I am looking for a Directory plugin/function to add a directory to my site. I would like this to be integrated without adopting the look of the directory package. For example, I would like the directory features to operate within the page or blog content column of my site. One could access the directory from a sidebar/widget link. Does anyone know of such a plugin? I don’t want the directory function to take over my site because I have many other existing features (a blog, static pages of content etc). I am also looking at the Genesis theme (Eleven40)as a future purchase. Within this theme, the directory content would display inside the main content column. The most important features would be a selectable country/state/city taxonomy and customizable content fields.

I would think this is already in existence(without having to hire a programmer).

Ideas? Thanks!
