Okay, let’s tackle this. So Eduardo has skills that could be in demand in Miami, but they're quite broad. Manufacturing and interior design aren't typically high-paying fields, especially without specific certifications or experience in high-end design. His language skills are a plus, but not necessarily a significant factor in determining his earning potential. Given his education from the Universidad de Buenos Aires, which is a reputable institution, I'd estimate his rate to be on the lower side of the spectrum. Considering his skills and location, I'd estimate around $75 per hour, which is relatively low compared to other professionals in similar fields.
