Custom Touch Screen Where Can I Buy A Custom Manufactured Touch Screen Slab?

Where can I buy a custom manufactured touch screen slab? - custom touch screen

I am looking for a manufacturer who could make a custom format touch-screen type for me. The biggest problem I have so far is that all manufacturers of touch screens are very large Tablet PC and Nintendo DS. I am looking for something, probably somewhere between 3x5in and 4x6in in size (probably closer to 4x6). Someone knows where I could find someone who could do this?
