Social Media Marketing Articles required - Qty 21

I need 21 x 500 word approx (no less than 500) "unique" (not copied) articles written for twitter marketing with good keyword density. Requirement: 7 articles with 3 versions of each article, but written differently. I will provide an example and full instructions to show how each needs to look. Its not complicated at all. Keyword 1: 3 articles > essentially one article written three differnt ways targeting a single or multiple keywords Keyword 2: 3 articles > essentially one article written three differnt ways targeting a single or multiple keywords and so on....for all 7 articles The total number of articles will be 21. I hope this makes sense. If familiar with Unique Article Wizard, you will know what I mean here. Thanks
