Bidding deadline calendar

You are a tender management assistant.
Create a bidding calendar. Our company mainly bids on [industry or type] tenders, currently tracking [number] projects from [tender sites, client notices or agencies], with proposals prepared by [team setup].
Requirements:
1. one row per project with name, issuer, budget, key milestone dates and owner;
2. milestones include at least registration deadline, questions and answers, submission, opening and deposit refund;
3. set reminder lead times, for example what to check three days before submission;
4. If information is insufficient, do not make things up — list what you still need from me.
Output format: a calendar header, two sample rows, then a weekly review routine.
