Write articles for review website

Running a review website aimed for the US market where i want to review tools and also write regular informational articles.

Right now there is a plan for about 40 articles both reviews and info articles and if everything works out good with the website there will be more.

You need to be great in the English language and of course also master the writing language.
As said at the moment there is 40 articles in the plans with maybe more to come. Articles will be between 500 and 3000 words depending on placement of the article and of course if there are things to write about said topic.

We want the same writer for all articles for the reason that while studying for the different topics you also learn about the subject and the articles will be better and more informative.
