What you might produce could be worth money. Consider whether you might patent the idea and then sell it to someone?
Otherwise, this isn't that hard to do. You could probably contact someone in China and they'd be in a container on a ship within a month (if you wanted 10,000...).
I'd say you need a microcontroller at the centre of this, obvious other bits like a piezo-buzzer and buttons. For a one-off, look around here (SEARCH Arduino), if you think this is a winning product talk to people who know how to make them.
That's about the limit of what I can help you with, but you can always ask again, with more details in your question - someone else may see it and have a better answer.
