Up/Down Counter - Large Display

Hi I'm new to this forum and am in need of some help in building a up/down counter 3-digit (1-999) to be used at our local BMX track to show the riders which moto (race) number is up. I've seen one at another track, which is a 2-digit display made up of bulbs where each number is about 1.5 feet tall by 1 foot wide. The operator pushes a button and he manually counts up.

The display needs to be very large to be visible during the day and I'll have to enclose it in some type of weatherproof housing.

Any suggestions on making something like this would be appreciated! Please keep in mind that we're all volunteers, so cost is a factor. It doesn't have to be too fancy.
