Correct Grammatical mistakes and proofread

I need someone who is a native English speaker to check 10 articles to make sure they make sense and are grammatically correct. The work will be submitted eventually to a directory that will only accept work if they are grammatically perfect, so please do not apply unless you can deliver work that is grammatically perfect. The first series of ten articles is a test case there will be at least three jobs a week available if you do a good job. Possibly as many as one series a day, because I have more work than I can handle at the moment.
