In a previous life, my company used to design and produce/print wall planner calendars, for accountants , solicitors , school photographers, etc ,with the contact details on about that company, and they could post them out to their own clients,
For example an accountants wall planner was April / March , a school photographers was September / August , and of course if their client put the wall planner on the wall phone numbers, website , logos etc were seen by people everyday..........
I don't know why I have'nt thought of this before , I am going to design and have printed a wall planner to give to potential customers............................
