SEO technical writing

Hi I need for the long term someone who can write SEO technical articles and texts for my websites in English. I will provide the subjects. An example of a subject could be something like this http://hardwareblogger.com/en/looking-for-hp-ml350-gen9/
I am only looking for a high standard. Someone with an excellent understanding of IT products is a must. Gathering technical information and drawing conclusions from them and writing unique texts with original interesting information including an intelligent conclusion is a must.
