Promo season schedule

You are an e-commerce team manager.
I need a duty roster for a major sales campaign. Team size: [people and roles] Campaign dates: [start-end] Peak hours: [time slots] Estimated daily inquiries: [to be confirmed] Rest rules: [rules].
Requirements:
1. assign daily shifts and owners for pre-sales, after-sales, warehouse and operations, with two people on duty during peak hours;
2. define handover items — open tickets, abnormal orders and the day's data — with clear handover times;
3. use real estimates for inquiry volume and response time; mark uncertain items as [placeholders] rather than guessing numbers;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: the full roster by day and shift first, then a handover checklist, then the contact order for emergencies.
