Okay, let’s calculate this. Melissa has skills in investments, equities, and portfolio management, which are in demand. She has experience as a commodity broker, which suggests a level of expertise. However, her education and location are not explicitly mentioned. Considering her skills and experience, I'd estimate her hourly rate to be around $120, which is below the average for finance professionals in South Africa. This is likely due to her location and lack of explicit education information. For context, finance professionals in South Africa can earn between $150-$250 per hour, depending on experience and location. So, my estimate is on the lower end of this range.
