Articles with quality in various topics - repost

I need some articles about different topics. They have to be 100% original (will be checked by Premium copyscape), to include quality and interesting information and to be likeable for reading. Also, is very important to be with no Grammar, Spelling and Vocabulary mistakes. My budget is 1$ - 1.5$ per 500 words depending on quality of the article. If you want more please do not bid. The articles have to be written in English language. A little sample of work is always pleasantly welcome. Thank you in advance.
