Okay, let’s tackle this. So Ender Soydan has 44 years of experience in the industry, which is extremely long. Marketing experience is valuable, but the duration is unusually high. Typically, marketing professionals with his experience might charge higher rates. However, considering the lack of specific skills mentioned (like digital marketing or data analysis), I'll need to make an educated guess. In Türkiye, marketing professionals with similar experience might average $50-$100 per hour. Since Ender Soydan has a degree in Kimya Müh. BS, which might not be directly related to marketing, I'll err on the side of caution and estimate a lower rate. Maybe around $100 per hour, considering the industry and location.
