I have a website and need a booking page added that can sell event tickets for my guided tours. Visitors should be able to pick a tour date, choose the number of tickets they want, enter a promo code, and complete payment through a secure gateway. Core features to build: • Tour date selection calendar • Quantity counter with real-time price update • Promo-code field that instantly applies discounts • Integration with Stripe Checkout Sessions. Acceptance criteria 1. I can pick a date, set quantity, apply a promo code, and see the total update. 2. “Book Now” sends the customer to the gateway’s sandbox, completes payment, and returns a success message to the customer. 3. Order details (date, quantity, total paid, promo code) are stored in a simple JSON file or database table that I can view. Feel free to ask any questions that will help you estimate time accurately—I’m ready to get started.
