Aboutus.com clone with added functions

I'm looking for a clone of [login to view URL] for a different market with some new functions. It has to be built on Ruby on Rails. if easier it can also be built on Mediawiki. These are the functions I want to to be added to start with: Added support for Twitter integration Social bookmarking possible It has to be possible to generate 190.000 pages fast and easily with content. "Bulk page creation" must be a function. On every "wiki post" Display video search results from youtube, vimeo, dailymotion, [login to view URL] Display images from google image search results and yahoo image search results. Possibility for users to add rss feeds. Possibililty for users to embed videos. User profiles can be created and will be automatically linked to their wiki page. Google map function. There will be more functions added on later stages so this is the start of the project. If it goes as planned you will be hired for more work. I hope that you understood what I'm looking for. If not, please ask.
