Article Phrase Rewriting, Software assisted

!!! FOR NATIVE ENGLISH SPEAKERS ONLY !!! I need someone to help re-write 5 articles with phrase variations. These 5 articles are already written (about 500 words each). You are not expected to do any research. What you have to do is "plug" alternative words/phrases into the article sentences. You'll need to add at least 4 alternative words or phrases in at least 4 places in each sentence - on average. You need to make sure that each alternative you add is 100% grammatically correct in the sentence. See the example in the next paragraph. {The work|This task} can be done {manually|by hand} like this - but the software below makes it {a lot quicker|much easier|a LOT easier}. You'll be using a software tool called PowerArticleRewriter. (There is a trial version that works for 14 days. If you work with me in the future, then you get a licenced copy.) Watch the video here to see how it works. [login to view URL] With the software you basically paste the article in a bottom box, highlight the section you want, and write alternatives for that section in a top box. If this project goes well I'll give you more articles. It is a fairly easy and straight forward task that can be completed fast. When you bid, let me know how long it'll take you to complete. I'm not a perfect english speaker so i let check your phrases by another native speaking english speaker. I pay only, if everything is error free.
