Design & Develop webpages for a new Web 2.0 site

Building a Web 2.0 site for my startup in the social media space. It would have one splash page for users to sign-up/sign-in, one page explaining the how it works section, one page on about us and team, and the rest two-three pages would be the main interface of the website that would include friends, their activities, their personal links and transparencies that would show content of their personal links. The sign-up/sign-in splash page would have 5-7 key messages with one message being displayed at once, and then after a couple seconds it slides to give way to the next message. We can discuss more on the project as we move forward.
