Hi Iranpolisci,
I have worked a few years in my university's writing center and have a fair amount of experience with ESL students. I was wondering though, what are your expectations for this process? Are you just looking for cosmetic work or substantive critique as well? I'm asking because, in my experience, I have found that they are both important (and to an extent, interrelated).
Anyway, to get to the point, yes I am interested, but I would like to know more about what you want out of it first.
