Hi Debra -
I'm a member of MomPack too and saw your email! I thought it was a great idea. I was all set to respond, but I got sidetracked, and then I saw your post that you'd had such an overwhelming response already, so I figured that I'd hold off. Plus I found some software to create my own biz cards, so I decided to give it a shot.
I'm really glad to know that it worked out for you! I may have to come up with my own little freebie or discount to build my portfolio and get some good contacts!
