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; but, I also did some blog posting, article spinning, audio transcribing, proofreading and editing (both for my work and the work of other people), etc.
For original articles I usually charge $2.5 per 100 words and for rewriting & proofreading $1 per 100 words. 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
