Does anyone here have a mill and would be able to manufacture a small item for me out of Ally Alloy?

Quite happy to cross palms with silver / beer tokens / make charity donation.

I have a lathe and pillar drill but no milling machine - can no longer get stuff done through the back door at work.

I have the material to make the item and it is only about 100mm square x 16mm thick.

Have it out for quotation with a couple of machine shops, but think it is going to be expensive even though pretty simple.

Thanks.
