Arduino proximity BLE relay project

I would like help with a small Arduino project including both programming and designing a circuit diagram. The target is this Two relays (12-48V) should be controlled over bluetooth. One of the relays should be closed when an authorized cell phone is within range, and swiched back of again when the cell phone is out of range again. The other relay should be controlled from the very simple cell phone app with one button to make the relay switch. The task is as follows: Design the software and program the Arduino code for the hardware. List the needed components Draw a very simple circuit diagram
