I am an excellent resource for this type of thing, as I already ghostwrite blog posts for a number of businesses and other types of organizations. While I write for a lot of law firms, I also blog for a number of other organization's, as well.
While I am new to the Freelancer platform, I have a great reputation on Elance/Upwork, which I derived from nearly a decade on that platform. I specialize in copywriting. I have a strong ability to write copy that is compelling and easy to read. I concentrate on high quality writing, not just filling in word counts. I am highly skilled with SEO, but I place keywords into articles without making the articles hard to read of unnecessarily awkward.
I have been doing this kind of thing for a long time, so I know what I am doing. The bid is for one blog post and I can do as many or as few as you'd like. Again, my approach is based on quality, not just churn. You give me the subject and I will have a quality article by the next day. Thank you for your time...
