50 articles on webmaster seo tools with high quality content

I need quality articles explaining about various webmaster seo tools that are available. I'd prefer an article on each tool, making it 50 articles in total.
I don't want copied articles, and me being an article writer myself, i know to differentiate quality and plagiarism.
And i just don't have enough time to write posts by myself, thats why i am asking this service.

Regards
