Blog post writer

I would need a person who can write and then spintax for first and last paragraphs of blog posts. We have a huge database of keyword-categorized unique content blocks (travel related), however we don't have the first (openings / introduction) and last (closing / conclusion) paragraphs. We would need a writer who creates a number of variations (e.g. 10) of a keyword related - but generic- first and last paragraph and then manual spins these on sentence (10 variations) and word/phrase level (3-5 variations) to human readable and grammatically correct paragraphs. Each spintax we would need to be able to generate a minimum of 500 copyscrape proof -min. 90% unique- paragraphs of each 75 - 150 words. For the right person this will be a recurring (weekly) assignment. See attached document for more information.
