Proof reading of articles - regular work

I require someone that preferably has English as a first language to proof read 4-10 articles per month. The articles are mostly around 500 words each but there may be a 700 or 1000 word article from time-to-time. As I am from Australia, you will need to make sure the spellings are localised for Australia. Australia uses the same spellings as the UK. You will also need to check the articles are grammatically correct. The articles don't need to win any literature prizes but should be reasonably grammatically correct and free from all spelling errors. Please PM me with your prices to proof 500, 750 and 1000 word articles. This will be continuous work.
