Details: - Occasion: e.g. 40th birthday, baby shower, company holiday party - Date and time: date and time - Guest count: number - Venue: home, rented space, outdoors, still undecided - Total budget: amount - Constraints: e.g. kids attending, vegetarians, small space, no alcohol - Vibe I want: e.g. intimate, lively, formal Deliver: 1) A budget table splitting the total across food, drinks, decor, rentals and extras, with a suggested percentage and the reasoning behind the split. Hold back 10 to 15 percent for surprises. 2) A menu that fits the budget and the constraints, with quantity per person. 3) A countdown checklist covering 4 weeks out, 2 weeks out, 1 week out, the day before and the day of. Each item with a suggested owner. 4) An hour-by-hour timeline for the day, from setup through guests leaving. 5) The 5 most common mistakes for this kind of party and how to avoid each one. If any number doesn't fit the budget, say so plainly and propose two possible cuts.
