5-10 Articles Per Week, Ongoing, Topic "Skincare products"

This project is for 5-10 articles per week on the topic of "Skincare products" mostly Anti-Aging Skin Care products but can be other skincare products too, beginning as soon as possible. Articles should be between 400-550 words. Articles should be SEO friendly, and will target 1-3 keyword or phrase per article. I will provide the list of keywords/phrases. Each article must be well researched, informational, completely original, grammatically correct, and pass Copyscape. You agree not to resell or use these articles again in any way. All articles will become 100% my property. I will provide the link to the website/products that I am trying to promote, which you can use for some of your research, I will also provide the link to my Pre-Sell site, so you know where readers will end up once they are done reading the articles you write. Please include in your bid how long it will take before the first articles are delivered, I fully expect the first few articles to take a bit longer to write as you get to know the products being promoted. I am looking for a long term relationship and I have another similar project on a different topic, which I may post later on. If your work is good I will give you first pick on this other project. Please bid only if you can begin immediately, and have the required time & skill, please provide writing samples. Flexibility is given, one week you can write 7 articles and the next 6, 10, 5, etc...
