Create Rivet Backed 3D Metallic Silver Letters That Are To Be Attached To Leather Facia

I would like three 3D metallic capital letters created. The letters are to be of the Maddac Font set which can be viewed here at this behance.net website - https://www.behance.net/gallery/19645737/Maddac-Font . Each letter is to be 50mm high and 30mm wide. Maybe with a raised height of 2mm. I would like to discuss possible finishes/looks for the letters - however, I am leaning towards letters of sterling silver with natural tarnish. To help you create these letters I have some technical drawings of the letters - if they are not attached below I can send them to you. The letters are to be permanently attached to leather surfaces - the leather will have a thickness of about 1 to 1.5mm. To make that possible at the back of each letter there needs to be three or four rivet posts - please see the ‘A’ attachments showing below. The four prongs at the back of the A are not rivets but this diagram is a good approximation of what is required.

If you and I cannot meet in person we will have to think of a way to ascertain whether what you create can actually be perfectly riveted unto a leather surface.

IN CASE IT IS NOT CLEAR: This brief requires the silver 3D letters to be created and couriered to me.
Please bid whatever you want to create these three letters. If you create awesome letters I might want more letters created.

Apart from these letters there are other silver hardware pieces that you might also be able to create for me.
