Hey, I'm willing to give this a go for the price stated ($1.25 x 5 x 7 = $45.5/week). I believe I'm pretty fluent in English, as it's the only language I know. I'll gladly take a test to prove myself. I have plenty of free time, so writing a bunch of articles is no problem. :)
Best of luck to you on your project, whether you choose to work with me or not.
