Hello! Sorry for the delay but the Holiday week has been hectic!
It's ok to submit the translation. I am still looking into the pay rate if you win, whether it would be paid as an Original or reprint work. I will let you know as soon as I do. Thank you for the question.
Even better news, it will be paid at normal Original work rates for first U.S. publication. So the same as Original works. Looking forward to seeing it! :D
