One-page dashboard for one sales or analytics API

I need one single-page dashboard that reads one outside account and shows daily numbers in charts. I will pick the source before work starts: Stripe, Shopify, YouTube Analytics, or one CRM. Only that one source. Not all four. The page should show about five metrics that matter for that source (for example revenue, orders, or views), a daily chart, and a date range. It should look tidy on a laptop. A Python Streamlit page is fine if the charts and the daily numbers are the same. Milestone 1 (₹8,000): connects to the one API with my key kept out of the page source, and shows the main chart plus the headline numbers for the last 30 days. Milestone 2 (₹12,000): date filter, a small daily table, and a short note on how I refresh the data. Hand over the running page plus how to start it. Out of scope: ads manager, a second data source, user accounts, and mobile apps. Please bid the full ₹20,000 if you can do both milestones with the one source I name. Budget: INR 15000–30000
