counter with remote

I need a counter show in a 65" lcd, it will have 5 numbers , something like the picture attached but the final design will be determined. This counter will show people entering a store. The counter advance by remote pulsations of a person out of the store. I need it asap, and the remote batteries must last at least 20 hours. I think easier way for display is a large pic with a predesigned counter inside.
