You should ask for referrals and you should also ask if you can use them as a case study for your website. After referrals and case studies you should probably divide your time between sales calls, cold emails and content marketing, i.e. white papers on technical topics, blog posts, short videos on your topic of expertise. Better badly produced videos that a potential customer can find than planned well produced ones they can’t find. If you’re confident enough in your skills as a trainer giving classes/courses in person is a wonderful way to build a name and helps a great deal with the book. It is very good to have a book you authored on the topic, even if it is a slim book. Slim books can be the basis for expensive courses, which both make money and serve as advertising.
