Article Writer needed for 10 articles on Google Plusone

I need around 10 articles on Google plusone. I have done the research work and will provide the keywords on which you need to write the articles. Some points to be consider are- 1) Article length- 500 words 2) Keyword density should be 3-4% only. I will give you a link to an online service to check the keyword density. 3) You must write SEO compliant articles- use keywords in heading/title, sub-headings and bold them a few times. 4) Only bid if you are able to write upon the technical and social impact/effect of plusone in general in SERP and SEO etc. 5) Must be 100% original, grammatically correct, copyscape passed and with great value for the reader. Please quote monkeyman in your bid so that I can know that you took the pain to read it to the bottom.
