Add additiona features to my Directory script 9/30/10

I want my Business Directory script able to: 1. possibility to include listings under different categories. Let's say that I have a website named [login to view URL], I can submit the website under the following categories: Search Engines, Portal, Business Directory. Up to three [login to view URL] approval required. 2. possibility to integrate videos in FEATURED listings in the PHOTOS tab of the listing page. No videos upload only videos codes from YouTube and others major videos websites. Also, please make the PHOTOS tab more elegant and well designed. 3. possibility to select featured ads for main page. The script is actually showing 3 random featured listings but, I want the admin to be able to pick random or select the featured listings to display on home page.
