5 Bodybuilding/Fitness Articles - Need unique well researched articles

We require 5 original and unique articles that are grammatically correct with good structure. The articles are about 5 different subjects within the bodybuilding/supplementation/fitness industry. We will provide you with the keyword phrase for each article. They all need to be at least 500 words in length and have at least four paragraphs. Sub-headings would be preferred throughout the article for quality enhancement as well as a short description of the article. Each article must use the keyword in the title, first sentence and the body for 2-3% density. I must stress that the articles MUST BE UNIQUE and will be confirmed with various sources such as [login to view URL], [login to view URL] etc. If you do not feel confident that you can write grammatically correct articles in English that are original, please do not bid. Any poorly written articles will be rejected, this includes many spelling mistakes, punctuation errors or failing Copyscape.com. Please place the TOTAL cost that you expect to be paid for the project and the TOTAL time you expect it will take, NOT the cost/time per article. We are looking for an ongoing relationship with some article writers for our website which has been in operation for 10 years in the bodybuilding industry. If this first project is a success, you will be hired for many future articles. Good luck and thank you for bidding.
