Booqpad has a series of agenda style iPad cases that look pretty much like what you're looking for. It has the card slots of the business cards, a pad of paper, and a place for your pen/stylus.
I was able to get one of these for my dad at my local Microcenter and is available on Amazon as well
Edit - I forgot to add that there's no camera hole for this case
Thanks for all of the advice. I ended up going with the iFrogz Summit which has a small business card holder, stylus holder, and can turn into a stand.
