Marketing

[Shalom Boaz Dishon]

First off I apologize if this is the wrong place for this. What I was wondering is the nitty gritty of getting started on direct mailing. I heard about the yellow cards which interest me but is there anything special about them or can I just go down to the local print store and order a couple thousand of them? Also is there some automated service out there that will deal with mass mailings or do I just stamp them individually and drop them off at the post office?
