Each project has vastly different needs, so the amount of time to complete it will also vary. Usually even a small project will take at least few days to complete (see: Why it takes a week to write 1 page of copy).
Once you’ve completed the Project Brief, I’ll be able to give you a reasonable estimate on how long your job will take, but you can find ballpark estimates for various projects on my Copywriting Rates page.
Your ability to review the first and second drafts of the copy within a reasonable time will also impact how long the project takes. I usually allow 48 hours for you to review your drafts and return them with any edits that may be needed.
If I’ve not received any feedback from you within 2 weeks of sending draft copies, I’ll assume you’re happy with the work and will close the project unless you’ve notified me of anticipated delays (in which case I’m quite happy to reschedule edits for your project).
