I have spent a lot of time as a freelance transcriber. I type at just over 100 WPM with 99% accuracy. I can perform very quick turnarounds on any videos or audio files that people need transcribed. I have always paid very close attention to my grammar and punctuation to minimize the need for my clients to edit the transcripts. When it comes to freelance writing, a lot of the same principles apply. I can perform quick typo-free quick turnarounds with proper punctuation and spelling. I am very careful to fact check whenever I write about something that I am not absolutely familiar with.
