Okay, let’s tackle this. So Marcella has 15 years of experience in environmental consulting, which is a specialized field. Her education from the University of Montana adds value. Location is Helena, Montana, which is a smaller market. Environmental consultants with her level of experience in smaller markets might charge lower rates. Maybe around $50–$100 per hour for a junior consultant. As Marcella has more experience, she might average $75–$125 per hour. Considering her expertise and location, I’ll estimate around $75 per hour.
