15 articles researched & written in perfect English

Hi I am looking 15 articles to be written on insurance. Typically each article should be between 250 - 400 words. I will provide the 15 topics, and at least 1 link for reference. The topic is researchable on the web, and not too technical. Your English should be perfect in both grammar and tone. Ideally you are a first language English speaker. The tone of the articles should be relaxed yet informative. Similarly you should be aware of optimising keyword density to the article topic. I expect the written articles to be 100% unique, and to be exclusively for me. I will expect you to confirm this on delivery of your work. Please provide links/samples of the quality of your articles. I will ignore all responses without an accompanying PM. I look forward to us working together. Thanks.
