Hi,
Your project sounds very interesting and I'd really love to work on it.
As for my experience here, I've been working as a content and article writer, mainly; therefore, I did a substantial amount of proofreading and editing, both for my work and the work of other people. I have acquired Cambridge Certificate in Proficiency in English (CPE).
I work for $1.5 per 100 words ($7.5 for 500, $15 for 1000, $30 for 2000), so if this seems fair to you and fits your budget, then great - let's get started right away :)
Should you have any questions about me, my work or my experience, I'll be happy to answer. In the meantime, see my reviews and kindly consider my proposal.
Kindest regards.
Isidora
