Article writer for Website

I have a need for a skilled English writer to articles for a medical website and blog. We are a health care and pain management company, so our writer should be interested and experienced in those topics, be a good researcher, and respect deadlines. Articles should be written so others will refer them to others in their support groups or forums, or our reps can give them to specific customers. The articles will be of two types: 1. SEO CENTERED: I will give you a list of keywords, and for each keyword. The pages will cover different specific topics and conditions, so you have do research to bring interesting and 100% relevant information. Good basic knowledge of seo is required as part of the process I require you to do is cross linking and back-linking my targeted keywords. The keyword/keyword phrase needs to be in the article title, first sentence and used another 10-12 times throughout the article for a total keyword density of 2-2.5%. Am looking for good quality article re-writers. The articles need to be informative to the reader with 100% correct grammar and punctuation. Article should be 400-600 word.
