Articles Writing & Websites Posting

We need serious service providers to work on a constant project for us. Project consists of articles writing, and posting the ready articles into free social media websites(we will provide the list with the websites). You just have to write your article as we need it, register for an account in the specified website, and make a page with your article, posted on the page - article posting is a very easy and fast process. Articles must be UNIQUE - that means each page must have a unique article written for it. 1 article length should be about 250-300 words. Results with the ready pages with the posted articles, should be send to us in an .xls file, containing the following information: created page URL(where you have posted the article)/user&password (login info) for the page/e-mail&password used in registration. Please, when biddig, advise your price for 1 such article posting, also your daily articles postings limit, and how long you can work on this project for us, taking in mind that this project may become a constant work for the chosen service providers, if we are satisfied with the provided results.
