Need 15 x 500 word articles @$2.50/each

I'm in need of some talented writers for a small project which may turn into a long term partnership. You MUST have EXCELLENT English writing skills...If you don't, do NOT bother applying for this. I'm willing to pay $2.50 for a 500 word article. I am looking to have 15 articles written within a 4 day time period, and far more articles to be written in the future. To be considered, you must demonstrate experience in writing HIGH QUALITY SEO articles by providing two (2) samples of articles that you have personally written. Article requirements for this project: * Content must be informative, interesting and concise. Not filler or fluff. * Only unique, original content will be accepted. Each article must pass CopyScape. * Must be written in conversational American English, with perfect grammar and spelling. * Must use keyword in the title and first sentence of the paragraph. Also, the keyword must be used throughout the article for a total of 2-3% density. * Each article must be proofread for spelling, errors, grammar and word count. I will provide keywords and/or long-tail keyword phrases for each article. More instructions will be provided in PM to qualified service providers. Deadlines must be met strictly. Thank you!
