Hi.. newbie here so pardon the ignorance.
I'm looking to build a 2 digit up/down counter that has a rather large LED display. This is to be used in an office setting so staff can see by the displayed number how many are waiting to be seen. The receptionist would push the up button as more clients arrive and the down button as the number decreases. Also a reset would be handy. There is no need for audio tones to signal changes. The 2 display digits should be 12-15 inches tall and preferrably green in color.
I have seen a commerciallly available product that is very close but has some additional features that are unnecessary and would add to cost.
Here is a link to the one I found so you have a better feel for what I am needing.

Here is link to a site I found that has pretty much everything for circuitry but I would need the large display and the way to integrate them into this circuitry.

Thanks for any help / advice. As usual, we would like to keep the cost at minimum... and on the display, it would be great to have an enclosure method like the finished product link shows so that it could be hung from the ceiling or mounted to a post.
Thanks again!
