I'm a former journalist (sub-editor/writer) of many years' experience, now freelancing for selected clients. My writing and editing skills are second to none, and my English is impeccable. If you're after a professional editor to give that extra polish to your copy - or even to rewrite it completely - you won't be disappointed.
My minimum hourly fee is AU$40 for proofreading, rising in accordance with the complexity of the task. Please ask for a quote.
