Buisness card design

I need a business card design, for a kids only clothing store I am about to open. The card must have our logo (attached below). We would LOVE if you can design a card that can be used by kids, to create something else with the card. It must be something that only uses the card...like maybe a paper air plane on the back, that kids can make...or? I am not really sure what, so I am totally open to suggestions. It must be for kids however, so easy because my target market are toddlers. I want a clear design, I like clean designs that are not cluttered. The logo must be on the card, my contact information and a spot I can add promo stickers when needed. I want to have a black and white back ground colour made, and would appreciate a few samples, so I have options! :) When you reply, please MSG me with your portfolio, and what your cost will include (revisions...and so on) When you really please include your ideas for what the card can made into....if this is not included, I am sorry..but I won't go with you. Thanks!
