Job Aggregator Script/Plugin

Hi freelancers, I need a simple script which will pull RSS feeds of jobs ordered by categories with sorting features or advanced search features. I also want to be able to add RSS feeds in the administration panel to pull jobs from various websites. I would also like clients to be able to add their RSS feeds or their job listings for pay (they can pay with PayPal). Clients would have their own admin panel to manage account, listings and payment. Paying clients would have their listings shown in the "FEATURED JOBS" section on the site. planning to have 3 different pay plan and packages. We'll have the ability to add text and content to each category page. Example: The site will have different categories like Government Jobs, Accounting Jobs, Web Development Jobs, etc. When a user clicks on these categories, he/she is taken to a category page with a Brief Description and a listing of jobs being aggregated under. (I will need to add the content myself...). When a user clicks on individual listing, a scraped description would be displayed also; then a link to "external source" will be displayed at the bottom to read full listing. Will have a pagination feature also, sorted from: most recent -> oldest listings. Users will need to sign up (with one of the following: Facebook, Twitter, Google or manually) before they are redirected to the actual website where teh feed/job originated from. They can be done in an iframe or fixed header bar at the top showing category drop down/search box so they san still go back and search on our 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. MOBILE: Will need to be mobile ready using: [login to view URL] The mobile site will have the same feature as the regular site. Reference Sites: [login to view URL], [login to view URL], [login to view URL], [login to view URL] and [login to view URL], [login to view URL] Please note that this could be a wordpress plugin. We are not necessarily looking for a standalone script, this could very well be a wordpress plugin.
