Okay, let’s tackle this. So Kassimir Slabakov has a Master’s degree in Fine Art - Carving, which is a specialized field. His 43 years of experience as a self-employed artist is also a significant factor. Location is Miami Beach, Florida, which is a high-demand area for artists. Considering his education and experience, I would estimate his hourly rate to be around $75. This is a relatively low estimate compared to other artists with similar experience and education. However, this is a rough estimate and may vary depending on various factors such as his specific skills, portfolio, and client base.
