24 articles of 400 words

I need 24 articles written on a variety of subjects for the purposes of search engine optimisation. They don't need to be researched, just well written, with meticulous grammar and punctuation. Each article requires the incorporation of a specific keyword three times within the body copy, but without sounding 'salesy'. Each article should take no longer than 25mins to write, so you would be averaging over £10 per hour. Please see the attached sample as a guide. Work would strictly need to be completed by Sunday evening (22/7/12), so you would ideally need to start today - Saturday, 21st July.
