User Interface Design / Social News Site

Hello, we need a sliced design in clean and valid HTML+CSS for our social news site. The designs should cover the front page and internal pages of the website: 1) landing page(registration/login) 2) internal pages: 2.1) politician profile page with a few profile details and a place for links/comments 2.2) user profile page with information about the user 2.3) user communication page 2.3.1) form for adding news(text/link) similar to Facebook design 2.3.2) user stream with possibility to comment and add opinion to the topic or a specific comment 2.3.3) dynamic modal window for display of notifications, forms, etc. Please make it useable with different sizes(no full background images, that have to be resized in order to use smaller size) Additionally all icon and other miscellaneous content(like buttons, thumbs up/down buttons, etc) must be present too. The site functionality will be similar to www.quora.com, but for targeted group(sites will be aimed at people active in politics) Summary of tasks: - create 2 very similar website designs(similar concept, different design) - clean and valid HTML+CSS files - logo that is easy to recognise and good for branding(original concept) - jQuery to be used for the UI where needed(Please keep in mind that the site will be done with heavy use of AJAX, so the design should be build with the concept of dynamic pages without refresh. We will take care of the backend and the overall functionality, just please don't use any tables, or similar technologies that don't work well with heavy AJAX websites with dynaic content) - full UI to be developed and to be verified by our developers before approval and release of payment Let us know, if you have any questions.
