I have had quite a lot of experience in writing articles, business proposals, academic papers and book manuscripts for clients and for myself. Some of these are available in my portfolio, many are available in my personal writing portfolio at: http://www.writing.com/authors/vaughanjones . In my Guru portfolio are also a number of referrals and recommendations from past clients. Please take note that my fees are negotiable on the number of articles to be edited and on the term of the project.
