Hello.
I've an experience with starting a whole smart home system with Arduino and with an Android app for my house, and we are(Me & Friends) are doing market research on this, trying to build a startup in Egypt.
Anyway, your task is pretty basic and can be accomplished in 2 days for 30$.
If I got awarded, I am going to need the details of this "Selection" process , is it key-entry by a keyboard, or a list of names pre-programmed? Both can be done.
I can also,vl for future projects, refer you to some DIY sites that can help you develop pretty much anything yourself.
Best of luck!
