Small, wireless, non-bluetooth keyboards. Answered

I own a 1st gen kindle fire. I use it alot, and bring it to school everyday, and was trying to figure out how to get a keyboard for it. It doesn't have any bluetooth but I have it rooted and as shown here custom kernel can get you far http://www.youtube.com/watch?v=-F79sLcFwTU. I was wondering if anyone knew where to acquire a keyboard about 7" that is almost flat and doesn't use bluetooth but is still wireless.
