Hello, I believe that your work is easy to accomplish. I am an Australian who knows the 'Queens English'.
If you don't mind me mentioning it, I feel that the pay rate of $0.50 cents is very low. I do not think that you will get the right sort of professional bids at that price.
My bid is therefore much higher for the article paraphrasing ($3.00 per article). I can re-write a few articles each day for you.
You will not waste your money, it will be money well spent.
You will have a professional job done, and if you select me, you will pay me each day or each week, via Paypal.
