To book a measure and photo appointment, the following steps must be taken: 1. Find a suitable hour-long time slot for the appointment where both a photographer and measurer can be present, including sufficient travel time. 2. Confirm the sales package choice between the Online, Traditional, and Hybrid options, noting the package on the appointment. Check with a manager about any discounts. 3. When confirming the appointment, remind the vendor about needing a signed contract, ID, proof of ownership, and EPC completed beforehand, as the property cannot be marketed without these items. Reconfirm package choice and consider upgrading if possible.
