Church map/direction card help

I know I asked for some help on this issue in the past....now I am needing some more help. So here's the scoop. My church doesn't have direction/map cards for me to send out in the invites. I have them from the hotel and for the rh. Majority rules that the proper thing to do is to make them up....I really don't know where to begin. What format to use? What programs? If anyone was successful with this task....I would greatly appreciate words of encouragement!! TIA!
