Have a local marketing co. doing some work for us. All summed up...heres what we get 4.25x6 postal card Concept, copy,graphics,finished art work Printing:full color on one side with full bleeds and two color on mailing side. Mailing list:30,000 local homeowners Est postage=$5700. Estimated cost for fliers=$6100. Marketing co. feels this will get about 900 responses...from that, he feels about 300-350 new customers will be aquired. Any thoughts?sound about right?
