A focused technical conversation about one decision — not a general introduction and not a sales call. You send the pre-read material beforehand so the session starts with the actual problem rather than with context-setting.
The deliverable is the written output afterwards: a scoped outline for follow-on work, whether or not you use me for it. That is yours whether or not you engage Lars for the follow-on work.
If you do not have all of it, book anyway and say what is missing. Turning up without material is still more useful than guessing at a scope on your own.
