Android Telegram Market Mini-App

I need a compact Telegram-based mini-app that will run on Android and let local shoppers buy fresh fruit and meat directly from my market. Within the chat interface customers should be able to:

• Browse a clean, searchable product listing with photos, prices by weight or unit, and daily stock indicators.
• Place and confirm orders end-to-end, choosing delivery or pickup and receiving an automatic order summary.
• Chat with us in real time for questions or special requests, without leaving the mini-app.

Because buyers often pay before collection, please wire in a reliable payment gateway (Stripe or any comparable solution you recommend) so checkout happens seamlessly inside Telegram.

The build should follow Telegram Bot/mini-app best practices, handle basic inventory updates from my side, and produce an APK or deployable package that I can install on my Android devices.

Deliverables
1. Source code with clear comments.
2. Installation and setup guide.
3. One live test session showing listing, order flow, chat, and successful payment.

If you have previous Telegram bot or marketplace experience, let me see it—speed and clarity are important so we can start selling right away.
