Recreating Yelp! (a review community website)

I am looking for a team or a dedicated coder who can help me create a website from scratch (or using Drupal or some other open source platform) that is capable of the following functions. Basically, I want to recreate [login to view URL] (visit it now if you have not already). * Users of my site should be able to create an account with picture, profile, ratings, points, etc. * Users will be able to post stories, links, rate locations, events and products and designate where those locations are using a Google Maps interface. * The site will be ad based and feature Google AdSense * The site will utilize Google Analytics This is a very high level general overview of what I want, I am looking for a coder who understands what I need and will not require micro managing. You are free to develop the site using your chosen technology but it needs to be cross browser compatible (including cell phones) fast loading, and reliable. I do not want a vulnerable site, I expect major traffic. If you do a great job developing the site I will plan on keeping you as support.
