Custom Made Square Metal Snap Button

I am in need of a manufacturer that is knowledgeable in the garment industry and can make a mold for a custom snap button and then be able to produce them on a large scale. the snap i am looking to make is a 8mm-11mm square metal(preferably brass) black snap button. I have attached some pictures of the prototype snap that i am looking to make. To be better explained, the pictures are of a simple sew on snap button. What i did to modify it and how i would need them to be made is..The male side of the snap would need to have its 4 corners bent back as seen in the picture, while still having the male nub sticking out. pretty simple/basic. The female side of the snap are currently being sewn on my garments but i am looking to make it into a prong/socket set or "dye" set. where the female can just be pressed onto the garment. In order to do so it would need to have a small prong backing as seen in the picture(just an example, i know its round),i would need the snaps to be square not round. If hired to do the job i will follow up with more details on the project. i am aware that a mold would have to be made to get this project done and a minimum order of pieces to be placed.
