Discord Bot for Role-Based Newsletters

I need a skilled developer to create a Discord bot for my server. The bot's primary function will be to send out weekly newsletters to server members, depending on their specific roles.

Newsletter Content:
- The newsletters will consist of text, images, and links. The ideal candidate should have experience with creating bots that can handle multi-media content.

Role-Based Distribution:
- The bot should be able to identify which members to send the newsletters to based on their server roles. This will require an understanding of Discord's role system and how to programmatically access it.

Ideal Skills:
- Experience in developing Discord bots
- Proficiency in programming languages commonly used for bot development, such as JavaScript or Python
- Knowledge in handling multimedia content in a bot
- Understanding of Discord's role system
