Okay, let’s tackle this. So Alvin has 27 years of experience in audio engineering, which is a long time. His skills include audio editing, engineering, post-production, and live recording, which are all in demand. He’s worked as an engineer, which is a specialized role. Location is Smyrna, Georgia, which is a smaller market. Industry standards for audio engineers in the US range from $50 to $150 per hour, depending on experience and location. Given Alvin’s 27 years of experience, I’d estimate his hourly rate to be around $100, which is at the lower end of the range.
