Okay, let’s break this down. Neil has a broad range of skills, including interior design, sustainability, and construction. While these skills are valuable, they don’t typically command top dollar. Interior designers and construction experts can vary widely in their rates depending on their experience, location, and industry demand. In the US, especially in a suburban area like Park Ridge, NJ, I’d expect Neil to be on the lower end of the scale. Considering his skills and location, I’d estimate his rate to be around $125 per hour, which is roughly in line with what I’d expect for a mid-level interior designer or construction expert in this region.
