Modern Earth-Toned Soap Box Design

I'm seeking a designer to create a modern style soap box for my soap line. It should be:

- Made of recycled paperboard, reflecting my commitment to sustainability
- Designed with a minimalist, modern aesthetic
- Using an earth-toned color scheme, in keeping with a natural, eco-friendly theme

Ideal candidates for this project will have experience in packaging design, a strong understanding of modern minimalist design principles, and a passion for sustainability. Please provide examples of previous work that align with this project.
