Develop APP with profiles for web and iPad

We need to build an application that enables my visitors to create their own PDF file with people that are important in a business or market. My user can add people to a horizontal list of people, remove them, or rate them as being important. Then, their selection is saved by a cookie, or the user can connect with Facebook. The application should be built on open web standards. Front end compatible with iPAD and standard web (safari /explorer). I have built a clear prototype in azure. You can see it here; <[login to view URL]><wbr /> In your offer, please state clearly what technology you will use and some references. The design is also important but can be separately offered.
