Don't want to P on your parade, but we've tried all sorts of advertising including these monthly local ad mags, golf club brochures, doctors surgery calendars etc etc. Never had a single enquiry so made a rule never to get excited about them again and decline any offers, firmly but politely.
Only advertising that ever worked was in local parish magazines and even this has dwindled to almost nothing over the past few years. If it wasn't so cheap these would have been given the elbow too!
