Raised Wooden Letters

Hi Guys, I'm just in the process of drawing up a three piece cast iron door system for a new wood heater and I'm just wondering if anyone knows where I can purchase raised timber letters for attaching to the patterns. I found a couple of US suppliers, but I was hoping for something local, preferably in Melbourne.
Thanks for any help.

Edit: Just found a similar request posting earlier this year and it seems Spotlight was the preferred supplier. I was hoping for something more specific to the pattern making industry.
