Okay, let’s tackle this. So Rachel has a solid foundation in design software like Photoshop, InDesign, and Illustrator, which are in demand. She also has experience with 3D modeling tools like Rhino and Sketchup, which are useful in sustainable design. Location is New York, which is a hub for design and creative industries. Considering her skills and location, I'd estimate her rate to be around $125 per hour, which is slightly below average for a designer in this field but still competitive. This rate is also influenced by the fact that she doesn't have any senior or executive-level experience, which can command higher rates.
