We need English copywriters

Hi! 

We are a content development agency looking for a copywriter with excellent English skills for one of our current projects.

We need articles reviewing certain products and comparing them to one another. We don't need salesy and fake articles talking about how awesome a certain product is. The writer should google the product, read a couple of item descriptions/reviews about it, make an opinion, and summarize it in the article. Each article has to be 400-500 words in length. We need many articles like that, so this is a long-term opportunity.

Requirements: 

- Excellent English, links to your writing portfolio / previously published blog posts. Experience of writing product reviews will be a plus

- Ability to complete your own research. Look at professional blog posts, amazon product reviews, forums, etc. You are required to make an informed opinion about a product.

- Absolutely no copypasting (using other people's articles/reviews from the Web word-to-word). 

- Reasonable availability via Skype / email - respond to messages in 24 hours.

Please, in your bid, give us your rate for a 400-500 word article.
