Social Engine Mod To Create, Post Articles and Rate Articles

I have a Socialengine site and I am looking to have a new mod created that would allow users to create, post and rate articles. It should be able completely integrated with social engine features such as blogs, groups, etc. and allow for articles to appear on the homepage and in customizable sub-page topical categories. Users should be able to search articles, comment on articles as well as share them by tweeting and posting them to facebook. Some modifications to the site's custom template will be required to accommodate the features and functionality. It should also be easily managed through the Admin Panel. The quality and time to market on the mod is critical. I need strong Socialengine and strong Mod creation experience. I need quality engineering and best practices applied during the development lifecycle.
