Unfortunately, most of what you read about sales and marketing is meant for product sales to consumers, and that’s not what you do. Your business is high-end, relationship-based and costly. People are not going to buy from you until you’ve earned their trust.
You need an approach to marketing; sales lead generation, networking and account development that makes sense for you, and is manageable given your busy schedule. A coach will help you develop a plan tailored to your situation and marketplace, not the latest marketing hype and fads.
