Consultative Selling Skills for Experts.
Many experts are frustrated with their inability to engage prospective clients in a conversation about their project needs. (See Zintro feedback for examples). The truth is they don't know how. They tend to overwhelm the client with their enthusiasm and information about their product or services. Clients balk at this "hard sell" and back off. I have published a book on the subject and have 25+ years experience training sales people.
