100056 Customized Search Engine Site

I know that there are thousands of search engine scripts, however, I am looking to develop a search engine for video files and images. Below are required features: 1) The site should pull files from many rss feeds and crawl various seach engines to update and populate the search results every 15 mintues. 2) There should be an ability for registered users to comment on the video or images. 3) PPC ad intergration 4) Back end Admin panel to manage site Here is a link to a demo of a similar site to clone. This site works well but it only pulls from rss feeds and does not crawl the search engines. Demo: [login to view URL] The full features of this script are found here: [login to view URL] If needed I could buy this script for $50.00 and then the programmer for this project could modify it to also include the search engine crawling unless there is a better script for this project that could be produced are is already available.
