Article "Spinning" and Editing / Proofing

I am looking for the following skills: 1) I need to be able to send an article of 300 - 600 words. Have you place "spintax" within the article, "spin" article, place keywords in a 2-3% density, then proofread for errors. Candidate must be able to edit article to perfect grammar and spelling. I will pay $1.20 per 100 words for each fully spun and proofed article. 2) I also need a candidate who can take instructions and find specific types of articles, re-write to include 2-3% KW density, "spin", and proof / edit for errors. I will pay $1.50 per 100 words for these types of projects. Please send examples of writing. Thank You, Casey Connors
