I am building many large websites. The websites promote preventive health, healthy eating and exercise, nutritional supplements and will be a library of information (similar to webmd). I am looking for professional medical researchers who provide articles/literature to writers who speak and write english fluently. It would be ideal for the researcher to have good knowledge base and experience in health, nutrition, nutritional supplements, exercise, and weight loss. Being a good fluent english writer and knowledgeable about SEO would be an additional benefit.
