Hello, the bid price is just a placeholder. If you are still interested in this job, I am a sound editor with decades of experience, and I have experience in editing forensic tapes. I should check your raw audio to understand if it is audible ( by positive check, you will receive a short edited sample). Send me a cut of your audio, please, and then we can discuss your project and fix the final price! Thanks, Eli
