Write an Android application for MSc dessertation project

This is a MSc computing project which i initially started to do but due to my workload seems like i wont be able to complete so i need someone to help me out. Its An android application for doctor's appointment booking system. There will be three user 1)administrator who can create,edit,delete, view an user, create/update doctor's availability, check cancelled appointment and update appointment slots. 2)doctor who can edit/update own profile, check booked appointment and patient details.3) general user who edit/update own profile, register to the system, view doctors availability,user can view dictor's availability, book/amend/cancel /view appointment. The app would also facilitate the user to view doctor's profile, nurse's profile, available service offered by medical centre, contact details, editable about us page and different language translation feature. I would appreciate if you kindly provide the diagrams, database schema and any prototype that you will use to complete it.
