I am a long-time writer and blogger who's written for health care, insurance, finance and entertainment sites. I wrote for a financial website for several years (writing over 300 articles) focusing on the needs of women in particular as they manage their finances while they age. I would be happy to send you samples of my work for that site. I also covered the Presidential election and entertainment-based finance stories for the site as well.
For many years, I researched and wrote legal contracts, teaming arrangements, insurance policies, non-disclosure agreements, vendor licenses and legal position papers.
I have always used social media (LinkedIn, Facebook, Twitter and Google+) to promote any articles or blogs I have written and am always cognizant of writing SEO-specific articles.
