How to book

Ready to go? Here's how to get that work off your desk and onto mine


  • Email Kelly. Send an outline of what you need – this might include the word count, the page number, number of documents, deadline, specific style issues, level of intervention needed (proofreading, editing etc).


  • Quick response. I will review your brief the same day and send you a cost to approve along with any queries. I can also book a quick call with you to chat through your requirements.


  • Confirm the booking. Simply reply to the email, confirming you want to proceed along with your PO number, if relevant.


  • Put the kettle on. You can now rest assured knowing your project is being worked on by a qualified proofreader and editor.


It's as simple as that.
