Hi!
I have been working as a freelance writer for a while, and I often write about health issues, so I believe I could write articles you need in a way that will be satisfying for both you and me. I think the best article length is 500 words. It is enough to write all the necessary information, and avoid being boring.
My price is 0,7USD for 100 words, so 4 articles of 500 words would be 14USD.
I hope you will find my offer interesting, and I am looking forward to the possible cooperation.
Thank you for your time,
Emiljana
