Community website

We are starting a site that will display content and have multiple membership types with different profiles. For this site we have multiple schools advertising to students. The schools can create their profile which will include their calendar, photos, videos, description list available services and classes. Students also can create profiles where they may write about themselves and post pictures or video. They can comment and rate schools that they have attended as well. The start page will have a function to allow users to search for schools based on what programs they have available in what areas and what times. Also, we will have polls and charts. This site will be monetized at the start by displaying google adwords ads and later by charging for different subscription levels. I would like to have this functionality built in from the start. I am familiar with joomla and I would like to use joomla, community builder and cbsubs, but I am open to other frameworks as well. I am open to custom solutions but would prefer using a framework. We like the site [login to view URL] and it's layout. The functionality is somewhat similar as well. If bidding please be prepared to discuss this at length because the entire plan will be laid out before a bid is accepted. Also please include an hourly rate or example fees for maintenance after the site has been accepted. Thanks,
