Next piece of work

I plan to have a map of the world and put the number of missing people per day on different countries. I want to do this by having digital timers that can count up at different speeds....for example the USA has 2300 people who go missing per day, so I would want a counter that counts up to 2300 over a 24 hour period. The UK has 550 per day so I would want it to count up to that over 24 hours. These need to be fairly small to fit on the map and ideally flat.
