We run a mailing list which sends writing projects and requests to over 1000 English-native speaking, professional writers. This service is FREE for you to use. Last week our writers wrote over 750 articles for the site owners that sent us their projects. Simply use the following form: http://www.thewriterfinder.com/for-content-buyers-about-our-service/content-request-form.html Mailings go out Friday afternoons, and you can expect to receive numerous bids from qualified, native English speaking writers.
All writers on our list are, to the best of our knowledge, native english speakers. In addition, we personally review writing samples from everybody on the list, and you'll find most writers will also include a sample or two with their bid to you. Let me know if you have any additional questions.
Looking at the site is seems to be a bidding for work thing - any averages on what writers charge per word?
It really varies per project, I wouldn't be comfortable quoting prices here, since we put projects through to the writers for everything from articles requiring no research to articles requiring research, tech writing, press releases, product descriptions etc, and naturally the prices will really vary.
