Okay, so Alex has a strong background in architecture and design, which is in demand in Miami. His skills in Autocad, Maya, and Rhino are also valuable. Considering his experience and location, I'd estimate his hourly rate to be around $125. This is slightly below the national average for architects in the US, but taking into account his focus on mixed-use and interior design, which might be less lucrative, I've rounded down. However, this is still a reasonable rate for a skilled architect in Miami, especially when considering the cost of living in the area.
