Only one of the four is a booking
Three of the four levels need nobody to be scheduled. The downloaded pack, the working vault and the corrected vault are produced without a conversation: you pick, you pay, and the work happens. Only the £1,500 level↗ is a booking, because it is the one whose cost is somebody's time.
That line — between a thing agents do and a thing a person sits down for — is the line between the third level and the fourth, and it is the only reason the price moves as far as it does. {{claim:abp-correction-by-a-person}}
