With 11 years as a Creative Account Manager under my belt, I have been asked to review copy, amend copy and create copy. But by far one of my favourite things is being able to help someone change their tone of voice, re-write their own words, enabling them to deliver their message, in the best way possible. I would read your work, do a quick word count, have a chat with you to discuss your audience and your message, and look at any other documentation you may have to reference; and then quote you based on the time it would take to review and resend your fresh ideas. We would keep in contact though, and if you didn't mind I would run things by you from time to time, as these will still be your words, they are just being re-voiced.
