Graphic Designer Needed for Social Media Visuals

I'm looking for Italian graphic designers to create visual content (images, not videos) for social media posts based on texts I provide. This is a continuous job, usually requiring 4 to 8 images per client.

- Image Type: The images to be created are primarily promotional posters.
- Visual Style: The predominant visual style for these promotional posters should be colorful and lively.
- Platforms: The images will be used on Instagram, Facebook, and LinkedIn.

Please provide your cost per image for this ongoing project.
