Hello!
It seems that most people here might not have properly understood your requirements. It is a rather unique request, so I would like to double check with you on whether my understanding is correct. You actually want a BAD translation, am I right? And it has to be from a native Japanese who can speak English somewhat, yes?
I personally have a pretty strong command of English, as you can see, but I have a Japanese student who used to take English classes from me. She has difficulty understanding some words that have more than one meaning and tends to use them wrong, and her grammar isn't very strong either, but you can still somewhat understand what she's trying to get across. I believe this would be exactly what you are looking for?
She's just my student, someone who doesn't have a freelancer account, but I can get her to help you get this task done through me if you'd like :)
Hope to hear from you soon!
Mei
