Translate an English song into singable Japanese lyrics

Hello, my name is Bre and I need help from a lyricist who is fluent in Japanese. I’ve written and produced a song called “Humility” and put it out using an English version of the Japanese vocal synthesizer “Vocaloid,” and I would also like to put out a Japanese version as well. The new lyrics would be a “poetic translation,” meaning that the it doesn’t have to be exact, but needs to sound natural in the new language... that includes using native Japanese phrases / idioms, so it is relatable to that native audience.

Additional info:
I've written melody, but need help writing lyrics. The vocals will only be used for demo purposes. Not for release.. . I'd rather pay extra for the writing to be ‘work for hire' and not share publishing.. I'm an independent artist not affiliated with a record label.
