contest plugin wordpress

Hello, We are looking for a supplier able to develop a wordpress plugin for playing social networks. It is a game with the principle of sharing links similar to “Contest Burner” but much simplified. The plugin is registering participants with a username and email that can then retrieve links to share on social networks, only Facebook, Twitter and Google +. Participants can connect to their social network account directly via the plugin. A tracking system must exist so that the participant accumulates points for each share. Points are cumulated for each share or each click, and also when friends of participant share or register (sponsorship) . The classification of participants must be public, for participants and non-participants. Do not hesitate to propose us your offers. We will consider all proposals with interest.
