Content Writing - Introductory content on specific topics

I am looking for someone to research and write holistic introductory content about topics such as balding, weight gain / loss, skin ageing, and skin whitening. You can choose to write about one or more of the relevant topics. The write ups should generally include - an introduction about the topic, including the extent of the problem, who suffers from it, etc - what is happening biologically that results in such effects - what are the key causes of these effects and symptoms - what are the various schools of thought around solving the issues - different treatments available in the market Should include quotes and advice publicly made by leading experts and doctors on the topics, and other such anecdotes that add credibility to the content Must be suitable for a small website, and indicate appropriately the relevant reference sources and quoted sources from research, and give credit where required. Freelancers must be fluent in writing in English, with a simple and efficient style.
