English-speaking ghostwriter for ebooks

We are looking for a ghost writer who will edit high-quality content to our style. The content contains Americanisms, which we need to be converted to UK English or the UK English versions to be re-written.

We will use Copyscape to check...

The subject areas are online business, social media, small business, time management etc.

Each ebook contains no moare than 1,000 words, so we would need someone who can work through them fast. There are more than 10 presently, and we are lookign for long-term committment.

Thanks
