High-End LinkedIn Graphic Design

I'm looking for a talented graphic designer to create 50 premium-quality posts for my company's LinkedIn page. The posts should be original and not sourced from Canva or other platforms, and they should not be AI-generated. We want to ensure our content stands out and effectively generates leads.

The posts will include:
- Informative articles
- Promotional offers
- Client testimonials

Ideal skills and experience:
- Expert in creating high-end, original graphics
- Solid understanding of LinkedIn's professional tone
- Ability to design engaging, lead-generating content
- Strong portfolio showcasing similar work is essential

Please provide samples of previous work and a brief on how you plan to meet our requirements.
