electronic numeric display board for volleyball

I have searched the Internet hard for a reasonably priced electronic numeric display board to no avail.  I am interested in constructing a remote control scoreboard for volleyball similar to basketball scoreboards deployed in high schools.  For many years I have played and continue to play a LOT of drop in volleyball at various local Rec Centers.  It would be great to be able to keep track of the score with a remote control device in your pocket while playing the game.
Alternatively please let me know of any high schools being torn down which could be an opportunity to save a basketball scoreboard that would otherwise be relegated to a land fill site.
When you think about the utility of such a device, why hasn't this project been done before?  Maybe it has and if you have any info then PLEASE forward.   I would seriously entertain any posted price for such a completed device if it exists as the hero factor is huge.  The advantage of building it yourself is that you are in a position to manufacture duplicates for others and you become the repair man.
The bigger the display board, the better.  I know they exist but are mostly cost prohibitive.  At this point I am prepared to start with a small display for the prototype in order to get this project started since I am very enthused.

A giant clock would be nice but really overkill as only need a numeric display visible on the gymnasium wall from the court. I am interested in the details of your project for prototype purposes.

Its going to cost you. I built a giant clock for Y2K which is in my Instructables, to give you some idea of what's involved.
