Arduino Programming & Build

Project (high level): - Need simple counter with buttons to run on small Arduino board. - This project is multiple stages (this is stage 1) Project details: - Need something similar to this: (https://www.amazon.com/SC-SPORTCOUNT-90040-Lap-Counter/dp/B0016J9NE8/ref=asc_df_B0016J9NE8/?tag=hyprod-20&linkCode=df0&hvadid=191937239663&hvpos=&hvnetw=g&hvrand=4187674160277719954&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1016367&hvtargid=pla-338146517434&psc=1&mcid=e7a3264e644d38a98276cb7016f50ff1) - Small Arduino board, with small screen (up to 4 digits), and two buttons; one for counting every time its pressed, and the other (small one) for resetting the counter back to zero (when press & hold for a second). - Architecture must be provided in addition to the list of parts (so I can purchase it), and code (with instructions of how to download) - Most important thing at this project is the size of parts, I need the smallest possible board, and screen (screen still readable of course so I can package them later. - The counter button need to be capacitive touch sensor that works by touching any surface; human skin, metals, plastics…. (it has to be very sensitive for any touch so it can count easily). - List of parts need to be provided (in addition to instructions of how to wire it, and how to download the code to the boards) so I can purchase it and build the first prototype. I am open to any other methods / suggestions or enhancements.
