I about jumped out of my shoes when I saw that your Lodge Ceremony Team was writing the ordeal script. That's a No-No.
In reference to your original question, think of this as an opportunity for your chapter ceremony team! Help your youth recruit chapter members to take on this new responsibility! Until you have a rehersed team, invite a ceremony team from another chapter to preform at your Chapter Ordeal. As long as the ceremony Arrowmen are youth, it doesn't matter what chapter they are from.
Also, worse case senario, Ceremonialists are permitted to read off of the (established, National) script. It isn't as impressive as having the lines memorized, but it will work in a pinch.
