To whom it may concern,
I would like to offer my services for this job as I am available to complete it for 5pm (London, UK time) and because I have recently been doing a lot of proofreading in English for different companies, including communication agencies, autotomotive manufacturers, and more.
My level of English is native and I deliver the most professional revisions to my clients.
Please feel free to contact me.
Kind regards,
Catherine S.
