Hi,
I am familiar with writing for a variety of content and have years of experience writing online. I charge $8 for a 500-word article, whether it's a blog post or review, though I am willing to renegotiate depending on the complexity of the task and the length of article turnover.
I have attached a sample article which I believe is in line with your business. Please see my private message for a list of my relevant experience as well as other important details you might need.
