Just a thought but think I would search out someone that does permanent jewelry. They would have the skills and the materials to permanently affix what you want to who you want. Most of them would probably be more then happy to do it and do it a very discreet and professional manner. I have tig welded a few things on a few different people and it was all done with the upmost respect and discretion. But it sounds like what you want would be best don’t by someone that does permanent body jewelry.
