I need about 20 articles on travel destinations... paying 1 dollar per article.. and would like a sample of an article on Tai Chi so that I may view your writing skills - The articles need to be 500 words long, with good grammar. -The articles must use the keywords provided to you approximately once per paragraph - All articles will be 100% unique - content and will be checked for plagiarism / spam via several pieces of software. - You should have experience of writing SEO optimized articles - The articles should be written in a friendly tone and not be completely dry and technical. I will be looking for many more articles in the near future. I am looking for a dedicated writer or a team of writers to establish a long-term relationship with who can write quality articles in English with no spelling / grammar mistakes, for this project as well as upcoming projects. The articles must be good, properly researched, filled with content and no nonsense. Please do not be expected to be paid more than 20 for these articles, as I will have many projects forthcoming. The faster you can get the sample to me along with an earnest effort via communication and the lowest bid from a quality writer will ensure future projects
