Blog or website content writer -- 2

I am looking for someone to write blogs for our website that pertain to our industry of Indoor Playground and amusement equipment. We need about 50 articles or blogs written that are very specific to our industry that will help with keywords and our website rankings. The blogs will be as if we are the experts in the industry and know everything there is to know about the industry. Writing in fluent English with proper grammar is a huge must and the most important thing. We would then need 1 new blog per week as well so there is an ongoing aspect to this project as well.
