Build Order Automation System with Scheduling & Excel Reporting

**I am looking for an experienced automation developer to build a reliable order automation system for a specific online platform.** The system should allow me to: * Select exactly which product I want to order * Set the required quantity * Schedule orders for a specific date and exact time * Schedule multiple future orders * Automatically process the configured order * Confirm whether an order was successful * Prevent duplicate orders * Record successful and failed attempts in an Excel/XLSX file Speed and reliability are important. The developer should recommend the best technical approach using permitted APIs, integrations or browser automation. I eventually want a simple dashboard where I can select products, quantities and scheduled times myself. **Excel reporting should include:** * Product * Scheduled time * Actual execution time * Quantity requested * Quantity ordered * Price * Order/reference number * Successful/failed status * Error message if applicable **Development will be done in phases:** 1. Working proof of concept 2. Scheduling and multiple products 3. Simple dashboard 4. Further optimization and additional features The project budget is approximately **$2,500** and I prefer to work with milestones. We will start with a smaller proof-of-concept milestone before continuing with the complete system. **Please answer:** 1. Have you built similar order or booking automation before? 2. What technology would you use? 3. Would you use API integration, browser automation, or a combination? 4. How would you make the system fast and reliable? 5. How would you prevent duplicate orders? 6. Can you automatically generate/update an Excel/XLSX file? 7. How long would you need for the first working proof of concept?
