Robert Plank shows how a simple book can become a practical prospecting tool that helps local agencies win attention and clients. He explains that a book does not need to be perfect, long, or expensive, and can start as a cover, contact details, and even useful blank pages. The framework is to create a minimum viable book, add service menus or checklists, then update the print-on-demand file as ideas improve. He recommends using Amazon, Lulu, Canva, interviews, transcripts, and case studies to turn existing content into chapters. Concrete examples include $2.50 printed books, $2.85 media-mail shipping, 142-page networking books, and 99-page books sold as authority assets. He also explains audiobooks, compilation books, and private-label covers for clients. The most useful takeaway is to treat a book as a credibility-building follow-up asset, not a perfection project.
