Okay, let’s calculate this. Jessie has a certification as a Certified Interior Designer in Maryland, which is a good starting point. However, her skills in design research, interior architecture, and sustainable design are more specialized. Considering her certification and skills, I'd place her in the lower to mid-range for an interior designer. According to the Bureau of Labor Statistics, the median annual salary for interior designers in the United States is around $55,000. However, since Jessie has experience in construction management and project management, which can command higher rates, I'll round down to $75 per hour. This is a conservative estimate, as her skills and experience could potentially justify a higher rate.
