Based on location (Cathedral City, California), industry demand, and skills (Marketing, Advertising), I estimate D.g Cook could charge around $75 per hour. This rate is lower than average for marketing professionals in the US, possibly due to the lack of specific experience in a large corporation or a well-known company. However, as a business owner, D.g Cook may have developed valuable skills in marketing and advertising, which can still be valuable to clients. Average hourly rates for marketing professionals in the US range from $50 to $100, but this can vary widely depending on the specific skills, experience, and location.
