Fitness Trainer needed to write 100+ fitness articles (Project duration 3 months to 1 year)

Hey! I'm going to start a health and fitness blog. I need 2-3 certified/pro fitness trainers to write around 100-200 articles (700-1000 words each). I need SEO based content and I'll provide SEO data for writing a particular article. I need a few serious, reliable, and dedicated fitness enthusiasts to write 4-5 articles per week. Payment will be made per 10 articles (Milestone) - biweekly or monthly. I'm looking for someone reliable, dedicated, self-motivated to work with me. Write "I'm a fitness coach or fitness enthusiast" in your bid proposal. Else, your bid will be ignored. Thanks.
