asp.net event/community portal

Looking for asp.net event/community portal - something like [login to view URL] - only bid if you have existing portal that is similar to that website. Looking for fast completion and would just like to buy existing script - if you have a demo in asp.net then post your project demo and must post asp.net webb application demos - only asp.net so we can see what you have done before.
