I'm curious as to how much you spend advertising your services through the following mediums:
  • Business Cards
  • For Sale & Direction Signs
  • Promotional Materials (such as pens or calendars)
  • Direct Mail Campaigns
  • Mass Media Advertisements (such as billboards or bus benches)
  • Internet
  • Other
All of your input is appreciated.
