Take you cue from the big guys in business. They have sites but you see them on TV and hear them on Radio. I know it is the shotgun approach. But they have the money to do it.

But you and I can do space ads and don't forget classifieds. offline works better than on line. But email works at times too and forums. Classifieds on the net I am not sure but don't think people read them as they do in the paper or magazines. Ask your self: Do you read Classifieds on the net. I don't usually. In the papers and magazines I do.
