Upwork
I have over ten years of experience in writing and editing. In my time as a freelancer, I have edited millions of words for dozens of highly satisfied clients. I offer developmental, line, and copy editing services, as well as beta reading. I am also available for writing projects, especially involving dialogue or branching narratives, such as for video games.
Fiverr
I offer the same services on Fiverr, however due to their fees and policies, I highly suggest using Upwork for a better experience on both sides.
