My dear wife made cards from prints of some of my drawings. I think they came out quite nice. My first impulse is "let's sell them," but she made these for gifts. Truthfully, I can't think of a cost-efficient way to make and sell cards unless you are doing them by the multiple thousands. Not sure I could sell that many, so unless you have other ideas, get on my wife's good side and she might make you some. Assuming you want them, that is.
