Rewrite articles on our website for sales and SEO

We are a dog school in Norway. In a couple of weeks we are launching a redesigned website, and in that regard we would like to fresh up some of the text There are currently 4 articles up to 2000 characters each, we want to have rewritten as a start. - About the dog school - 3 Courses You will get the existing text and important points, and create good articles in terms of sales and SEO. SEO is very important for the courses. There is a keyword per course, and this must be highly ranked in google etc. It is also important that the text is really going to sell classes, so it's nice if you have experience selling services and knows what sells. Dog school is in Norwegian, but it's okay if the text is in English. I'll translate it myself. If this works, it offers more jobs. There are also 10 more courses that need an overhaul as well as other articles. Is there anything that is unclear, it is nice if you ask :-)
