Hello there,
I've been a writer and content manager for 7 websites, 3 of which I had set up on my own. I can write in different styles as needed, and in perfect English. I've also written medical articles for freelance work before, and like you proposed, these were carefully researched off the net and with some medical books we have around the house, although I have taken Anatomy as a college course, required by my major (I took dance studies), and am quite familiar with the various systems in the body.
I am also quite intrigued of the combination of "medical directory/tourism." I look forward to working on this project with you. If you need samples of writing, let me know.
Thanks,
Joelle
