Hi,
I am a native English speaker with a background in management and marketing. My specialty is writing high end content and copy for web sites, brochures, proposals and so on.
Rewriting copy into good English, while retaining 100% of the original meaning, is a special skill. Paraphrasing is something that I am good at – I was just born with English language skills, I guess.
From experience, I know that rewriting takes longer than writing fresh copy. Your 1,600 words is about 3 hours work at my standard rate of $29 / £22 per hour = £66 and I can complete it within your deadline of 4 days, probably on Saturday.
Thanks and best wishes,
Dan
