Rounded slot milled through 15mm Aluminium plate

Hi Folks. I looked at doing this myself but don't fancy my skills with hand tools.

Based upon the assumptions that I ship the material to/from you at my cost and its external dimensions are accurate, can you quote me for the production of the rounded slot (all the way through the material) as per the diagram please? The material is Ecocast Aluminium, 15mm depth.

Please advise. Thanks. Tony.
