Several years ago the author was tempted by extremely cheap rates for TUGboat advertisements, and declared urbi et orbi he was a TeX consultant. This audacious step lead to many interesting experiences. Some results of this work were published on CTAN and listed at http://borisv.lk.net/laTeX.html (the list includes both commissioned packages and the ones I wrote for my own purposes).
In this talk I tell about my past projects, big and small, and discuss the lessons learned from my journeys in the fascinating world of publishers, editors and authors. I describe writing book and journal styles, communication with customers and other issues relevant for TeX consulting.
