Job Aggregator Script

Hi, I need a script which will pull RSS feeds of jobs ordered by categories, I also want the ability to add or remove RSS feeds in the administration panel to pull jobs from various websites. I need to be able to search internationally by country. Each country to be shown on a separate search page. Ability to add text and content to each category page. Example: The site will have different categories like Accounting Jobs, Web Design Jobs etc. So, when a user clicks on these categories, he is taken to a category page with a Brief Description and Jobs being aggregated under. (Please note, I will add the content myself...) The jobs need a area ie Florida search and town ie Miami to drill down the search results. Smarty template engine to make it easy to change the theme of the websites(optional) Users see the search results then are able to click to view the job details and are re-directed to the actual website where the feed/job originated from. They can be done in an iFrame so there is a bar at the top showing a category drop down/search box so they can still go back and search on your website. Each job is an individual page on the website, seo optimized for generating organic traffic. Administration panel basic features such as ad management, modifying content pieces, user management User system for registration/login/profile/recommended jobs Reference Sites: [login to view URL] and [login to view URL]
