Hi,
I have looked at your project description, and the need to have an experienced writer, precisely health niche, a native English Speaker, understanding of SEO and the endocrine system. I meet these requirements, as I have provided articles regarding health for a client on this website, and I can share samples of the project I worked on, and the article as well.
I am also a native English speaker, and have provided content on many topics for clients on this website.
I am available to chat, and discuss this project with you right away.
Thanks,
