Small metal work job / casting a buckle and legs

I need help with a small metal-work project for a furniture sample - existing supplier has let me down so it's rather urgent! I need 4 little legs made and a matching buckle - the finish is a polished phosphorous bronze which is quite a pinkish copper/ bronze colour. This can be a plated finish on another metal if necessary.The legs need to have fixing holes to be fixed to a chair frame from underneath and the buckle is just decorative ie without a pin. Need very high quality finish and measurements have to be very precise particularly with the legs so that they don't wobble.

I have attached dimensions and happy to answer any questions.
