Need some suggestions for a movie idea I have

So I was at work yesterday and all of a sudden I an idea came to mind for a small short film. The idea is that of a pair of East German border guards who watch over a small checkpoint somewhere in the woods (think the two Czech guards from Stripes but a little less slapstick). I figured it would be a comedy and can be a mix of humor based around dialogue between the two of them and some visuals (people going to great lengths to get over the border, inspection etc). However I'm not to sure what else to do. I'm not all that familiar with them.

Anyway I'm posting here to see if anyone has any ideas whether they be ideas, jokes, plot points, uniform or policy info, places I can find info (like books or websites), or really anything. This would be just a short movie filmed for fun but I really like the idea.

Thanks.
