The Proof is in the Pudding as they say. When I talking to people, (word of mouth is still the best form of advertising) I tell them what I do, about the strength of the company and how log they have been around. I also will e-mail them copies of my last SFI Statement to show them what I can make a month.
I also let them know that they have my complete support and that I will be their if they need me.
