SEO Article Copywriting

We are in need of writers who can write proficiently in American English language for a long-term engagement. Only those fluent in American English and grammar need apply. Our main business is article writing (500-700 words) for article directory sites. You will be given a list of keywords and will write 10 articles on each. The articles must be informative, well researched and well structured. Content must contain keyword density of 3%, not to exceed 5%. The ongoing need is for several hundered articles per month. I will be selecting multiple writers as the jobs will be a minimum of 10 articles per project. Initial Budget is US $3.00/500 words. We will gladly pay bonuses of US $1.00 per article for truly amazing content that requires minimal proofing by our staff. Articles must be 100% your original work and free of copyrighted, plagiarized, or licensed material from a 3rd party of any kind, including offline material. I will confirm originality through several programs such as Copyscape, Plagisoft and others. I expect you to run the articles through online copy checking websites and/or software prior to submission. I am looking for writers who can begin taking on assignments immediately. All articles will be considered "work made for hire" under U.S. Copyright law. I will own exclusive and complete copyrights to all completed article content once delivered and paid. You may not distribute the articles in any way after delivery to me. Once I pay for the Articles I will own ALL publishing rights. Please PM bid and sample of your work. I prefer work to be submitted in MS Word doc format. Please mention the number of articles you can write each day and any favorite subjects. If this works out well and I am happy with your finished work, I intend on using your services for an indefinite amount of time. Pay will be through GAF escrow or through PayPal on a weekly basis or per 10 articles. Again, I am looking to develop long term relationships with a few talented writers. If you can meet my needs I will be more than happy to increase the pay as well as the amount of work offered.
