Need Article writer for social media marketing articles

I need good article writers to write some article on social media marketing, social networking and social media promotion highlighting the importance of Google Plus One in particular and FB and twitter in general. You must be aware of the technical side of Google Plus One as how it affects sites rankings in search results, how it can be monitored in Google Webmaster Tool and data on usage of Plus One over FB likes and twitter. I need these articles on an on-going basis, 3-7 articles each week. In your bid please provide me a link to your similar article that you have done before. Please send just one link or article to check and not a plethora of your previous work. Pay will be good if you can show up some quality work. Please include 'netavatar' in your bid so that I can check that you took the pain to go through my description till the end. Happy Bidding.
