Okay, let’s tackle this. So Alexandre has a mix of research, fundraising, and event planning skills, which are valuable in non-profit and sustainability roles. Location is Greenwich, CT, which is a affluent area. Non-profit professionals with similar skill sets in the US might charge $50–$100 per hour. Considering his skills and location, I’ll estimate around $80–$120 per hour. Let’s check averages. Some non-profit professionals with similar skills might average $60–$90. So I’ll estimate around $100, but given the lower end of the range, I’ll round down to $120.
