Hi! My name is Oliver and I’m a professional Audio Engineer of 13 years’ experience, 7 of those specialising in voice over production, including eLearning programs, podcasts, advertising, audio books, tv/film, corporate audio and much more. I have excellent editing skills and am also highly proficient with audio restoration / clean up software to remove any unwanted noise, clips, pops and bumps. I can work with and deliver almost any file format and will usually have work turned around within 24-48 hours. I’m based in Perth, Western Australia, so there may be some advantage to you in having someone who can edit while you sleep! I am also a voice over artist myself and you can listen to demos of my work on my profile page. These demos were also recorded, edited and produced by myself, and give a good idea of the types of work I have undertaken in the past year or so.
To answer your other questions: I use both Avid Pro Tools 2018 and Adobe Audition CC 2018 for recording/editing/mixing. For a project like yours, I would use Audition as it has superior options for exporting a large number of files at once.
For 40 minutes of audio, I'd estimate around 70-100 minutes work time, depending on whether the editing also involves removing mistakes, breaths, etc.
I would charge USD $25-30 per hour, depending on the editing needed. At the cheapest rate (for simple cut and export) that would be approximately $29
Thank you for considering my offer!
