Full Time Content Writer for Forums

I have 2 Forums that require a full time content writer. The subjects of these forums are general in nature mostly for students courses ie exams/board exams like Math, English, accountants, doctors, engineers and other exams like TOEFL, GMAT, MBA, GRE, driver license both for US and around the world, etc. This is an 8 hour work per day/5 days a week. Please bid per month or 4 weeks work. I am based in USA, but you will work in your countries day time so that is night time here in USA.. assuming you are from India or other Asian countries. I need the Provider services on an ongoing basis for at least 1 year. Contents are either articles, short topics, forum questions/reply, etc. Should be really good in English and knows correct grammar, punctuation, when to use upper/lower case. Please don't bid if you have problems constructing your sentences. Strong attention to detail is required. In your bid, you need to say "I am an expert content writer from" then add the Country where you came from. If you can follow this direction then that means you read my requirement and you passed at least the basic 'detail orientation' test. I will decline all bids the doesn't follow instructions. Thanks.
