Articles Written

I need thirty articles written which need to be about 300 words each. These articles need to be written in perfect conversational English. I really need to stress that these need to be written in perfect English! They will be used for blog posts, so need to be fairly casual style, not full of textbook type writing. I need ten articles each on three different subjects; I'll provide the keywords. I need these back within 5 days of selecting the provider. Must be original, will need to pass copyscape.
