Universal Python Telegram Bot Broadcast System

I am looking for a skilled developer to create a Python-based Telegram bot for me. The primary functionality of this bot should be the ability to broadcast messages to all users across multiple bots, all running from a single codebase. I currently manage several bots and would like to streamline the process of broadcasting messages across them.

Key Requirements:
- Implement a message broadcasting system that can reach all users across multiple bots.
- Build the broadcast functionality into a single piece of code that can operate all my bots.
- The broadcast messages will include both text and images.

Ideal Skills:
- Proficient in Python, with experience in developing Telegram bots.
- Familiar with the Telegram Bot API, particularly for message broadcasting.
- Prior experience with Python code that manages multiple bots is a plus.

Please note, the content of the broadcast messages will be a mix of text and images, so prior experience with multimedia message handling is desirable. The goal is to have a smooth, efficient and user-friendly system in place for all my bots.
