Build a feature similar to twitter and integrate into our existing ecommerce website

We have an existing eCommerce website and would like to build additional features. We require an expert developer/Developers to build a site similar to twitter and integrate it with our existing eCommerce features and website. The main twitter features will be on one of the pages that we will disclose to the shortlisted developers. Similar work is a must. Our website is built on PHP and MYSQL. Please use ILOVETOCODE at the beginning of your proposal for us to distinguish humans from robots.
