I'm thinking of doing the postcard method next week. AKA, selling ad space on a postcard then using the direct-mail program to send it out. Those of you who know have done it, know the program. Those who have no idea, do a search for "postcard." Were you successful? How did you go about it? I was planning on door-to-door, but isn't that solicitation? And most places frown severely upon that. Any tips are appreciated.
