Plugins for Social Engine SE4

I'm looking for following plug ins for SOCIAL ENGINE SE4 The social plugin is designed for Talent Acquisition, Fashion Sales and Marketing and Education Business Solutions. I have little idea about these plug ins. But I require something that can fit into a system which can simulate LINKEDIN or XING or VIADEO social engine plug ins for above applications. I intend solicitations from serious players only and I appreciate all the players who participate in this bid. Skills Required: PHP, SOCIAL ENGINE SE4, MY SQL, ZEND FRAMEWORK and any other skills that may be adequately suitable to build these plugins
