Good morning!
I am a native (UK) English speaker based in Derby, England.
Although you do not require knowledge of other languages, this is always a help to track difficult errors made by non-English writers - I have a good grounding in the Scandinavian and Latin languages that helps me do this.
I have many years of experience of proofreading - on Freelancer. Clients have been very satisfied with my work, which has covered several topics - e.g. photography, quality control, and web pages.
Only when I am confident my work is correct, will I send it to your client. If anything is unclear, I will refer back to yourselves to confirm understanding.
I do freelance proofing and translations full time, so I can offer you prompt turnaround times.
I hope these conditions meet with your requirements, and look forward to receiving your instructions.
Best regards,
Doug Lumley
