How to build a LED countdown with minutes set with a keypad?

I'm working in a audio/video studio and we broadcast videos from a computer.
I would like to construct a big LED countdown where i can set the minutes remaining to the end of the video with a keypad or a remote in order to be aware about the time remaining so that we can be ready for the next action.
Unfortunately, i'm not able to plan with electronics and so on, but i can solder and procure all the pieces.
Is there anyone that can help me?

Check out the projects listed to the right of this page. There are many similar clock/timer projects that use an arduino. So you can intergrate a keypad and whatever else you want.
