You are responsible for booking the officiant. If I recall correctly, when you fill out the info for the jacks pack, you also send your date and time. He may only send you a pack if he has the slot open. You can email him and he will get right back to you about whether it is open or not. He has been recovering from surgery lately though, so it may take a little longer. When he responded to me, it was within one day. He's great with email!
