Hi there!
I came across your job posting and am writing to express my interest in the same. I am a lawyer-turned-freelancer in the writing business since a little over three years. I also occasionally write on a variety of other niche topics such as health and nutrition, psychology, social sciences, criminology, weddings and fashion, media and entertainment, general content, etc.
I am myself into MLM and know how the thing works, about the good as well as the bad aspects of it. What aspects of MLM are you looking to get written as content? What is your overall purpose in approaching this subject - just educational/informational purposes for a general audience or something that you do yourself and need to sell? Once the purpose and target are identified, it will be smoother to focus on the content.
You have not mentioned how many articles you require, so I have kept my bid almost close to yours. We can always negotiate the final quote once we get to that stage.
