Tell me who the learners are and what they need to be able to do afterwards. That's usually enough for me to tell you whether I can help and how I'd approach it.
A short call — thirty minutes is usually plenty — about the learners, the constraints, and what success would actually look like.
You get a written outline: the approach, what I'd deliver, the timeline, and where I'd need your subject-matter experts.
Design, development, and review in stages you can see — so nothing arrives as a surprise at the end.
