Summer, its Dr Jon Hayes. You can search his name on this site, and google.
I've no idea how practical it is at that distance, but I expect you'd need multiple visits, getting blood tests and so on. If you do see him perhaps you can ask what tests are needed and somehow arrange them beforehand. He also does implants, which have the advantage of lasting a long time. I've not tried injections, but I'm pretty sure implants are better.
