Where to find The Nightmare Before Christmas figurines?

My husband and I are renewing our vows, and we've decided to have a big reception since we never had an actual ceremony or anything. We both decided instead of having our wedding cake to be The Nightmare Before Christmas, we would have a grooms cake that could be it. The lady that is making my cake will be making the curly hill that Jack walks on in the cemetery out of styrofoam. So the figurines have to be light! Or if any way possible, find a cake topper that has Jack and Sally both on the curly hill. I'd also like to have Zero, the trick or treaters, and Oogie Boogie. If anyone knows, please let me know! Thanks guys!!! :)
