To keep everything warm, you'll want to get a good box. This can generally be made out of anything but you'll want to get something cheap. We purchased a 22 quart styrofoam cooler from WalMart that usually holds drinks. These are disposable, and they can usually be found in the Lunch Box / Cold Box isle. If you don't find it at WalMart, go to your local super market or Walgreens. We found them there too.
You'll need to cut a few holes in the side for the camera, and pack some extra space for everything.
