Okay, let’s calculate this. So Brian has full proficiency in English, which is a plus. He also has experience in Pro Tools, which is a valuable skill in the audio engineering field. However, his skills in Spanish are only professional working proficiency, which might limit his job prospects slightly. He has some experience in Customer Service, which could be useful. But overall, his skills and certification don’t suggest extremely high demand or high pay. Based on national averages for audio engineers in the US, I’d estimate his hourly rate to be around $75, considering his location in Baltimore, Maryland, and his level of experience.
