Here is a few I've made recently.
Those are Corian pot with Annodized aluminum over corian. I've also made annodized aluminum over corian soundboard with an aluminum bottom.
I can make any of the items you are looking for. The only one I haven't made is the corian pot with an annodized playing surface and an annodized soundboard. But I can easily do that. It might break glass when you play it.
