birth announcement card design

I'm looking for a graphic designer who can not only design, but also come up with an original concept for a birth announcement card. For those of you unfamiliar with this kind of card. They are sent out to family and friends to announce the birth of a new baby. I'm looking for something original, not the typical card. So please, only bid if you have an original idea. Please describe the idea to me... if I like it I'll let you design it. The card is for twins. That's already an unusual fact, so let your imagination work. It would also be nice if you can incorporate the following keywords in the concept somehow: twins, mountains, bicycles. But this is not nessescary if the concept is good. Please only bid if you have an original idea. And only bid if you can provide a portfolio.
