Okay, so Mariela has skills in interior architecture, design, and related software like Autocad, Sketchup, and Photoshop. Her education from the University of Miami is solid. However, this is an interior design role, not architecture. The rate for interior designers can vary widely depending on experience and location. For a designer with Mariela's skills and education, I'd estimate a rate around $75 per hour, which is on the lower end for a designer with similar skills. This is a starting rate or a rate for a junior designer. As she gains more experience, she could potentially increase her rate to $100-$125 per hour.
