Arduino tally counter for hair transplantation v2

I need a tally counter for creating donor sites during hair transplantation surgeries. I need the schematics and code, since I don't have the time to work on them, but I can build the device myself. Basic functionality: The patient has an electrode (ECG electrode) on his hand. The other end of the wire is connected to a needle used to create donor sites on the patient's head. When the needle cuts through his skin, the circuit is closed, the device makes a sound (beep) and 1 donor site is added on the counter (of course it's displayed on a screen). The counter should be battery-powered and have a reset button and power switch. Additional functions: – a distinct sound for every 100th and 1000th site created – a small message above the counted sites like: "Donor sites created:" "1247", maybe even with language switching, clinic logo on device startup – "+" and "-" buttons for manual control – sensitivity adjustment – device should be battery powered – other details to be discussed
