I'm going to use a seperate directory script, http://www.idevspot.com/BizDirectory_2.php

You can see a demo on my site here: http://houstonlively.com/directory.php

Do a search for 'golf' and click on the sample ad I created. Feel free to click on the thumbnails, visit website link, and view larger map link. I added lytebox to jazz up photo viewing. You can also see frontend and backend demos on the developers site.

I'm just going to have businesses register seperately to place ads in see more the directory, since the average user will have no need to place business ads.
