24/7 Telegram Promo Bot

I need a simple Telegram bot that will post one promotional message every minute, non-stop, to a specific group. Each post must be text with clickable links so members can go straight to our landing pages.

Core behaviour
• The schedule is fixed at 60-second intervals, 24 hours a day.
• Message content can live inside the script itself or be read from a small txt/JSON file—whatever is quickest for you. I will supply the copy and links.
• The bot has to keep running unattended on a low-cost VPS or similar. If you prefer Heroku, Railway, Replit, or any always-on solution, that works for me as long as the bot never sleeps.
• On first run I only need one promotional message cycling; later I may add more, so leave the code easy to extend.

Deliverables
– Ready-to-run source code (Python, Node, or any language you like).
– Setup notes showing how to deploy and how I can swap in new text + links.
– A brief demo proving the bot posts in my test group for at least ten minutes without gaps.

Payment is a flat ₹600 released once I confirm the bot runs continuously for 24 hours.
