Look to other cultures and markets for this. India and Japan in particular have a massive variety of general and specialized containers in assorted materials, for whatever your needs might be. Europe/Russia and Nordic countries have more similar bakeware to the US, but since that's not how I normally cook, I'm not as familiar. I also have friends who are ceramicists, so if you have access to any, you could ask them what they'd charge for some custom glazed earthenware.
