Okay, let’s tackle this. So Barbara has 4 years of experience in environmental consulting, which is a relatively entry-level role. Her skills in environmental awareness are also in demand. Location is Bellflower, California, which is not a major hub for environmental consulting. According to the Bureau of Labor Statistics, environmental consultants with similar experience and skills can earn around $40–$60 per hour. Considering the industry demand and her skills, I estimate her hourly rate to be around $45.
