Okay, let’s tackle this. So Sébastien has a mix of skills like project management, environmental science, and public speaking. He has experience as a Conservateur de la faune, which suggests some level of responsibility. However, his education is at a gymnase de la cité, which is not as prestigious as a university. Location is Lausanne, Switzerland, which is not a hub for high-paying industries. Considering his skills, experience, and location, I’d estimate his hourly rate to be around $120, which is on the lower side for someone with his expertise. Maybe $150–$200 per hour for a more senior role or in a different location.
