Trial project - Article writing

This is a trial project. If you deliver per your previous references there will be many more. I need 20 articles, approximately 250 words, all original for a "Window Replacement". Note: the windows in a house not the Microsoft kind. Strictly no plagiarism. The written articles will be passed through copyscape. Each article needs to have a headline title, and 2% keyword density. Please only comment on the actual topic and not about other business/companies. The keywords will be given via pm. Each article should span about 200 - 250 words. - The main keywords should appear twice in the first paragraph (once in the first 90 characters) and twice in the last paragraph (once near the end of the text, if possible, in the last sentence) amongst other times. Please DO NOT just comment on the meaning of the keyword. I need up to date, current, informative articles!!! Please only send once all articles have been completed and please send in word document files. I Will Pay $3 Per Article & this must be started ASAP!
