Need a WordPress site like http://bit.ly/1glCqo9

I'm looking to have a site developed that has the same functionality as: [login to view URL] I can give you access to my account if you need to look through the site first. This site allows users to choose from pre-made templates. The user can then edit text, links, and images on the template. Some of the major functionality needed: 1) User chooses a unique user name after first signing up that acts as their page url. For example - [login to view URL] 2) After choosing a template, user can edit all areas (logo, images, text, links, colors, background, etc.). a. User can edit SEO settings (title, meta tags). b. User can enter tracking codes to header or body c. User can edit the colors of the template through a style editor d. Exit popup options 3) User can integrate Email marketing services with their template (Aweber, Mailchimp, iContact, etc.) 4) When a user is ready to "publish" the page, they can publish it live on this domain name, WordPress (need a plugin developed), Facebook tab, or download the html to put on their own server. Please look through that website, and feel free to ask questions.
