Articles with SEO

Looking for a long term article writer. I have many many articles to be written. What am I looking for? -Write informational and sales copy style articles. There are four types of articles I will be needing. 1) Articles for a blog with the intent of providing information and optimize the site for search engines. Example: How to become a rapper. 2) Articles about a topic, specifically intended to sell a product and optimize the site for search engines. Example: Information about fashion modeling to sell a fashion modeling Ebook. 3) Articles about a product, like a product review, specifically to sell a product. Example: Product x Steam Cleaner 4) Articles written specifically to build back links. So they have to be about the keyword provided and give some kind of lure for a reader to want to go to the website provided. -Create a title/topic based on the keywords given. -100% Perfect English, spelling, word usage. -Articles that flow and stick to a primary topic. -Someone who can deliver articles as they are written, quickly. -Someone who can SEO the articles. Bold, italicize, underline, where appropriate. Provide proper keyword density for the keywords provided 0.1 to 0.5. Not looking for hardcore SEO here, just the basics. What am I NOT looking for? -Articles pieced together with snippets of information. -Keywords thrown in sentences where they don't belong. -Sentences that are clearly placed in the article to make use of a keyword and add no real value to the article. -Articles that look like they were written by someone that their primary language is not English. (Whether your primary language is English or not) Ok, with all that said. When I give you an article to write, I will give you a keyword and tell you what type of article it is (one of the four listed above). I know your going to ask how many words the articles should be, I don't have set limits, but each should be more than between 200 and 1000. Please advise in your bid, how much per article, when your available to write, and how many you can deliver (average) in a time frame. Thank you and happy bidding.
