Just bear in mind that paying someone on fiverr doesn't make it less complicated. The problem of pronunciation exists whether you pay $5 or $500.
For example, the name of the recipient. Is it Kawai
Saneo? or Kawai
Jitsuo? or maybe
Kawagō Saneo? Kawagō Jitsuo? Or some other combination? It could be any of the above, plus a couple of other possibilities. To me, Kawai Saneo feels the most plausible, but I have no way of knowing the actual pronunciation. That is just the reality. If you pay me $5 for or $100, this doesn't change.

The best thing you can do is hope that your translator is honest, and will give you a list of possible pronunciations, beginning with the most plausible ones, and ending with the least plausible ones. So if that feels like an interesting endeavor, and you can find someone on fiverr who will do this sort of translation (which I'm sure there is), then that might be an interesting pursuit. Remember, it's not so much a problem of translation, as it is a problem of determining the possibilities and probabilities.
