483540 Yipit Clone

I need a daily deal aggregator for group buy websites just like yipit. I would like to have it more look like a combination of [login to view URL] and [login to view URL] Requirements: -Aggregate daily deals from different Websites, like [login to view URL],[login to view URL],[login to view URL] etc. - Design and features like [login to view URL], [login to view URL], [login to view URL] etc. As I said earlier I want a combination of [login to view URL] and [login to view URL] atleast for the appearance and feel. - It should be clean and defect free implementation * Info collected: Alexa Site Rank, Deal provider, picture, main title of the offers, description and information, Retailer Price, New price, Discount, Time left. Link to main website. -Ability to sort by city, by Web provider (snapdeal,taggle etc), by category, by deals expiring time, and ability to select one or more cities at once to display deals. -Ability to pull in automatically the deals and not only based on RSS feed (must have), may be with regular expression -Ability to add any other group buying website easily from admin back end. -Ability to categorize deals automatically. -Facebook and Twitter and other social plugin integration -Front-end: each city will have a pic that can be uploaded from the back-end. -Features like daily deals aggregator websites. -Each page will have a title, meta description, and Headers (H1) tags. -Built in free software -Built in XML Sitemap -Built in MySQL database -script property is ours -Must be secure -Must be error/bugs free -Inclusive of support for 1 year (or until we make any mods to the code). I need to add 20 sites and 8 have a RSS feed available. So I will need regular expression or some other method you prefer to add other 12. I am open to negotiations and also any comments and feedback are welcome to make site more user friendly.
