Unity 3d Developer needed, Camera Animation and User Login

The user must be able to login and recall their progress - it can be email, oAuth, I don't mind. I will provide the developer with the following Asset: [login to view URL] The developer will create a Start Screen with 4 buttons. Each button will animate the camera to a different screen on the model. and pause, waiting for the player to click play. When the player clicks play, a different canvas will be displayed to represent each individual game. The game is very simple, but I need the time of the interactions to be recorded to the database. for example, game 1 will be a number display sequence - the game will flash 2 numbers on a keypad - and the user will press the numbers in order. The timestamp of the button press must be saved to the database along with the game number and other information. If the user gets it correct, then the sequence of numbers increases by one, if they get it wrong, it goes down by one. THIS GAME LOGIC IS NOT PART OF THIS WORK, but the recording of a button click's time into the database iS REQUIRED When the user logs back in, their information is loaded and they carry on where they left off.
