Build a Rap Battle Plugin (Exact Reference Available)

I'll make this short and simple. I want a rap battle plugin (or just the software will be fine) that is EXACTLY like this one here: [login to view URL] This includes the side widgets and all. But mostly I want the software for the text battles. This would be the front of the Battles page: [login to view URL] This would be the sign up for starting a battle: [login to view URL] • I want a slight change from this page. I want it to be a callout system. So a user would search a different users name, and send them an invitation to battle. That user can either accept or deny the invite. • I do want the blind mode feature, where other rappers cannot see what you have posted until they write their rap. Contact me through here, email, or Skype. Email: rapforthemoment at gmail Skype: rapforthemoment This is what I want. Can you give me what I need?
