acquire a projector (if they even have those anymore) get a stencil of the image you want to draw and trace the image on the board.
not sure what kind of graphics shop might be availible to mids but if you know someone who might be able to get you a "hook-up" you could try and see if they would do some graphics for you - it's worth a shot
get to know the upperclass you're making the board for (that's if you still have a training board, 1st Sgt board, etc...) it's always helpfull to have their favorite theme/colors.
find the artists in your company as they always seem to draw some great stuff
