Hello,
I offer proofreading, editing, and transcription services of many kinds (whether it is books, essays, or transcribing Youtube videos).
As proof of my English language skills, I have passed the International English Exam (IELTS) with a score of 7.5, which is adequate for jobs like this.
I always try to contact the employers to ensure the job is completed to their liking and standards.
I hope to be of service!
