You've either attached the audio file as a project file or it didn't get uploaded correctly, because I can't see the audio file attached to the project.
I've got 4+ years transcription experience and can do your work on time without any issues, with great quality and accuracy.
I've currently put 2 hours as I don't know how long the audio files are and how many there are. Please let me know that so I can tell you a better estimate of how much time it can take me to do it.
I'm new on Freelancer and this is my first project. I promise to give you 100% quality work. Please give me a chance to prove my skills.
