Online Life Timeline App

I would like to get an online timeline app developed to visualize someone's life in a nice and graphical way! We would set the birth date and then add important events of life (wedding, childbirth, work, achievements, etc) with attachments (pictures, sound, etc). Later on, users would be able to connect their timeline to another user's timeline (in case of a wedding, birth, etc.). The app would also be able to connect to Facebook (and other social media) in order to grab posts and display them on the user's timeline. Access to the app requires to be secured with user accounts (login and password). This is an ongoing project and could become larger if the right development team is found. Thank you!
