Hello, I am newly certified home inspector, and I would like to get some advice on making a presentation at a weekly/ monthly realtor office meeting. Basically, do any of you know where can I get information, idea's, or topic's on what I should talk about? Has anybody ever presented to a group of realtor's before, and if they have, could they give me some pointer's? I also intend to offer the realtor's in my area 1 free introductory inspection so they can get to see what kind of service they can expect from me. Have any of you ever tried this tactic? If so, were the results positive or negative? What work's when trying to get business- that's what I would like ot know. I'd really appreciate any help that can be offered on this topic. Thanks in advance for your time and suggestions. yo yo
