Rewriting/editing of a number of technical articles

I've written a number of articles and I now want to publish them on my own website, but they need to be rejigged/rewritten. The sense and advice contained in them (which is all my own work) needs to be retained. I'd estimate that once you got the hang of it, they could be rattled through fairly quickly. Each article is between 1500-1800 words.

Graduate required (at least), native English speaker and high quality writer. This backlog needs clearing, and thereafter I need an excellent writer to provide content on an on-going basis.

Please give an indication of what you would charge to produce 2 rewritten test articles, and an indicative cost for rewriting 100 more articles. The deadline is around Christmas.
