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 am also holder of CAE (Certificate in Advanced English by Cambridge) and I worked as elementary-school teacher.
I work for $1.5 per 100 words, 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
