SEO Content

I am creating content for a website that will have articles of about 1500-200 words. In total, I will need about 10 articles for the initial phase. I can provide the guidelines from an SEO company of how each article should be structured and what keywords you should use for each topic. I can also provide an example of a company who used these guidelines and wrote these articles. Of course, we need to use these guidelines to write similar content but different for SEO purposes. Please let me know how much it will cost and how long it will take you per article. I am looking for someone I can trust to do the content for the website.

Thanks
Mikael
