Sorry English is not my first language.
You’re right. There are lots of personal attacks instead of helping each other. Yes, it’s sad.
That's why my first guess was "ESL?"...
Seriously, almost any good English student probably would be glad to help with editing (and, maybe, tutoring).
My guess is you might be able to find someone who would do it -- just for being publicly credited as "Script Editor" -- because that looks great on a résumé...
