Can someone write some code for me desperately and will be rewarded

I want to make a device which is portable and uses RFID to be able to monitor customers trying on garments. So the customer asks to use the changing room then I use an RFID tag and input the amount of items they are taking in and save that data to the tag itself and be able to reset and clear it with also an led screen. I'm not good with coding so this is a challenge to big for me and require a schematic of how the device will need to be hooked up
