Image Design for Blog Articles

I'm looking for a designer to create images for blog articles on an ongoing basis.

Here's what the work looks like:

I need a total of 30 designed images.
Types of images that you need to create:
- Cover/hero images for each article (used as the featured image on the blog and as social sharing previews)
- Infographics (vertical, shareable formats summarizing key points from the article)
- Charts and data visualizations (bar charts, pie charts, etc.)
- Diagrams and flowcharts (process loops, step-by-step flows, comparison visuals)
- Templates and mockups (document previews, matrix tables, checklist graphics)
- Pull quote graphics for social media

Style of the designed images should be:
- Clean, modern, minimal.
- No stock photos.
- Consistent colour palette and typography across all articles.
- The visuals need to work well on both desktop and mobile, and look good when shared on LinkedIn and Instagram.
- Most images should be 1:1 (square) unless stated otherwise in the brief.

I will provide complete details including content, data, dimensions, and design direction. Freelancer should design according to the details provided.
The delivery should include the source files as well.
