Electronic Jackpot Scoreboard project

Hey there.

Wondering if someone can direct me to the right product for this job. Or put their hand up to take on the project. 

I'm looking to create a jackpot scoreboard of sorts. Everytime someone pays a dollar at my venue, I want to be able to see an electronic scoreboard increase. So a simple push of a button should take the value up by 1. 

Hopefully someone in here can help direct me to the right product.
