magento social extension

Hi, I have got a web site that running on magento and I need an extension. This extension based on social share (like facebook / twitter) and discount. It must: - discount on the product page. not on pay page or cart page. - have a button on product page for discount. "Discount must be in product page" This is very important. - discount modes. (for example i should be enable or disable (for my brand and manufacturer's brand) twitter follow , post, facebook like, post, answer a poll, watch an ad, vs. ) - adjustable with attributes from backend. (for example -for 1. product fb-like: %1 tw-follow: %4- -for 2. product fb-like: %5 tw-follow: %1-) - detailed statistics. (discounts for days, weeks, hours / adjustable brands vs.) - not integrated with theme. It must integrate to magento. When I change my theme I still able to use this extension.
