I tried this a few years ago to get a stamp made up but the problem is in how to translate. Do you want the Chinese/Korean version of your name or the meaning of your name. In mine I had my full name translated to the meaning of each first and surname and put it in characters but it was a bit strange because Japanese people still wouldn't know your name. I'd suggest talking to someone of that language, maybe even a Chinese Take Away food shop or something, but make sure they're not messing you around.
