Jason: I would say your best bet for advertising would be local "senior times" type papers. We have one here called "golden years" they have all sorts of advertisements for seniors. And you are getting local qualified leads when someone calls. The 2nd base place would be medical equipment companies. They are probably the main competitors in your industry BUT they can be an ally. Cut a deal with them to build and install them. Then let them get their cut. Hope this helps... Ron
