Here is a video of a Rehearsal Induction.

This was the first rapid induction I did and it has never failed me. I learn it from a great book called Training Trances and have adapted it a little to suit my style.
Essentially you show the subject how you will take them into a trance, then go over it again, so it is clear, then once more just so they can really learn the steps, then...
Keep going. You never get to the actual induction. I find three of four rehearsals is all that is needed. I like it because it is quite permissive but rapid and results in a nice position of leverage - they have eyes shut and arm cataleptic.
Any questions about it then let me know.
