I have a B.A. in Creative Writing, have had many news articles published, and have substantial experience freelancing (although I am fairly new to this particular site). Each of these provided me extensive experience in editing.
It seems that the content you wish to be edited falls into the categories of Health, Food, Sex, Relationship, and Medicine. My latest freelance project was actually extracting relationship and sex articles from a book, and then editing them.
As a content editor for Magic Life Mantra, I would first read some articles from the site in order to get a feel for the way these articles are typically edited (grammar, style, etc.). Afterwards, I would proceed to edit the content according to universal spelling and grammar rules, but also taking into consideration the style in which this content is typically written. Articles about sex and relationship, for instances, tend to be written rather informally and playfully.
If you wish to discuss the project in greater detail, please contact me via phone or email.
Thanks for the opportunity!
