Battle Extension for Joomla 2.5 Joomsocial site

I do need a Battle Extension for a jomsocial site that enables registred user to create battles and post dancing videos to that battle. users should than be able to rate for the favourite dancer. the battle should have a time limit and close outomatically and announce the winner when the time limit is reached. The reporting data of the users battles should be shown on his profile. If possible it would be cool to have a admin option to reward the winner with jomsocial karma points.. It's a test project -> the budget is very limited thanks for quoting Oliver
