Develop Karaoke System

I need a karaoke application that connects with the Twitter account or Facebook or both (necessarily) because we do not know with which social network the user is most active. It is important not to store user data, I advise to use those integration by APP to access this app, as we use to see around. This application should run in a web necessalry or desckot environment or any suggestions that is necessary according to the experience of the professional. The user who log into the "system" choose a song for a total of 20 available, the system should allow store these songs by the administrator (unlimited) but for the user who will sing show the top 20 released by Adm to play. At the end he will receive a score that we will can post, but a few seconds of the this performance the "singer" will post to Twitter or Facebook his photo with the note in his social network. It is very important that the user data login not be stored in any database because it is confidential information. The application needs to run in an environment that allows touch screen, so use HTML5 responsive technologies, BootStrap etc. Imagine something like the the XBOX games dances system that gives the score at the end of performace, The post will be posted on the user's social network account login to share it. Suggestions are welcome, I am developer also but now I manage a company, so I'm hiring a professional able to perform this task.
