Need Help Removing Screw from Pulley

Hey Everyone, I've got this pulley that has a screw in the end, which broke off. I'm wondering if anyone can suggest how to get this screw out or a business that I could take it to that could do it for me. The Home Depot Pros grabbed it with a Vice Grip and cranked it and sheared it off. See Imgur links for pics: https://imgur.com/a/pZUtoBh
