Hello Beth,
I am a native English writer. I have gathered significant experience over the last two years or so as a ghostwriter. Unfortunately I am unable to provide you with a readymade sample as all my work is done for other people, who hold all the rights. If you require a sample, kindly send a title/keywords to me, I will do it for you for free! My bid is $3 per article. I can do 5-7 articles per week (it is a little, I know, but it will all be of the highest quality). If our collaboration works, I may devote more time to you and will write more articles for you. I hope to have piqued your interest. Thanks.
