Article writing and submission

I would like to have 15 (unique, thoroughly researched on keyword/subject) articles. Later to be submitted to 15 online directories (let me know list of your key directories) or I'll provide you with the list of 12 directories (6 categories in each for different keywords, total 72-75 links) . The articles will be written around topics related to business. The articles need to be approximately 500 words in length and should be encapsulated around keyword phrases (supplied). Title should be catchy based on the keywords supplied. For example, a title for an article on "business insurance" might read: "How to search for cheap business insurance" or "keyword". I want you to stick most common title formulas that include: How to, find "business loan" or "keyword" online, The Top 5 cheap business card or "keyword" providers etc. I will ensure that articles are copyscaped passed. So please only bid if you can do some research on the keywords before writing about them, else I'll ask for cancellation of the project later. Thanks Thanks
