The speaker outline, does that mean your bio or is that something completely different?
Great question. In your speaker outline I recommend you include your bio as well as an introduction so the host can introduce you well and create credibility for you before you stop on stage, your talk outline with 3-5 bullets of what you will cover, and of course a great head shot of you they can use on their website.
Voila! If you get these things in place you’ll be more prepared than 90% of the other people looking to get booked!
