Deal Aggregator

Needed: *Deal aggregator that pulls deals together from many deal sites with a way to easily add new sites. * Info collected: deal provider, deal's image like yipit or cake deal or better, Retailer Price, New price, Discount, Saved money, Time left, Amount coupons bought, Link to main website, anything you think would add value and make the site unique. * Ability to sort by city, by provider (groupon), by category, by deals expiring soon, and ability to select one or more cities at once & display deals. * Ability to pull in automatically the deals and not only based on RSS feed (which is mandatory) *Link to social networks * I have a site in wp now and want to add this to the main page of the site and have the rest of the site remain as well. At least for now. I need it to be bug free, Hot deals board will own the script, I'll need support for awhile. I was advised to ask about iframes? and for it to be included in sitemap? and other things... I would appreciate guidance with this... Thanks!
