Professional but simple Social Networking Website. - repost

Our project is pretty straight forward. We want a very easy to use, dynamic social networking site. We are new, so our budget is rather small however, as and if we grow, there may be future potential for you to continue to work with us With this project, we will be heavily involved with you in the Design aspect. We want the design very clean and simple to use, like for example, take a look at the new MySpace [login to view URL] . The project is NOT as complicated though but we really want it to be as clean and almost like a app. The features we want are the following (+/- a few) - Professional Profiles o Ability to communicate with each other o Update statuses o Find colleagues o Pictures o Attend events o Points for attending events (like awards for doing things system) - Profiles for students o Similar to above, but more restricted - Profiles for Businesses/Companies o Can post events o Invites Ability to change privacy and account settings and the usual Facebook type of features e.g. send messages, view people attending the events, news feed, ability to upload personal presentations e.g. point points about lectures for people to view.. Biggest thing about this should be the cleanliness for the design. Not sure what you will use to develop this but we have a strong preference to use Drupal. We want your recommendations and we will provide a full feature list once project has been awarded. PLEASE PROVIDE SAMPLES OF YOUR PREVIOUS WORK ESPECIALLY IF IT IS A SOCIAL NETWORKING SITE AND IF POSSIBLE WE WOULD LIKE TO SEE THE BACKEND OF YOUR WEBSITES - for example, how the backend of other social networking/CMS sites you have built are and how they are to use.
