FitBit Versa and Unity - 1 hour consulting request

I currently have a Unity-based children's game and I would like to develop an interface to the Versa Fitbit heartrate sensor. The one-hour consulting project should lead to a FitBIt App development project. I want the child to wear the Versa and display the heart rate in the game. The heart rate will be shown so that the child can see if the heart rate goes up or down. I want the interface to be written in C # calling PHP routines that access a MySQL database. List your FitBitdevelopment experience, and your familiarity with Unity, C #, PHP and MySQL.
