Community Portal

Looking for someone who has built a communit site/portal that they would like to sell. The portal has what I call weblets where everyone has their own video, audio, blog, content space, statistical profiles etc. what am I trying to do? creating a site that allows people to show case their talent whether it's music, art, film, etc. Since I'm looking for something immediately I was hoping there was a programmer who has a web portal already built. I'm talented in populating websites, and having lots of content.
