I understand what you are looking for.
I am one of 3 native English professional content writers. We have just finished a project with another American client providing 3000 words per day, per writer 6 days per week.
Our work is UNIQUE, gramatically correct and SEO friendly. We can write about any subject that we are able to research and are well versed in the use of keywords and hyperlinks where required.
We also employ a full time project coordinator who checks all aspects of our work including grammar, word count, keywords and copyscape as well as ensuring we meet our deadlines of 500 to 600 word articles in 2 hours or less and 1000 -1400 word articles in 3.5 hours or less.
We can start start on 2nd Jan (Tues) with one or up to three writers should you wish.
Please see our portfolio of the work we have produced recently.
We have been getting 45 usd per 1000 words but if there is high volume and long term work for 3 of us we may be able to negotiate on this.
The main reason I have chosen to bid on this job is because we are looking for professional clients who are looking for long term relationships, who will pay on time, have consistency of work, good communication and appreciate us and the value our skills bring. Your reviews on this site are positive from those who have worked with you before. This is very reassuring to me.
I would be happy to discuss this further over a private message should you wish. I look forward to hearing from you.
