Natural Landscape Design for Public Park

I'm looking for a landscape architect to design a public park with a natural aesthetic.

Key elements to include:
- Walking paths: These should be integrated seamlessly into the natural landscape, providing easy access throughout the park.
- Playground: This needs to be thoughtfully placed within the design, ensuring it's accessible yet maintains the overall natural feel.

Desired design style:
- Natural: The park's landscape should mirror the beauty of the outdoors, with an emphasis on organic shapes, native plantings, and sustainable materials.

Ideal candidate will have:
- Proven experience in landscape architecture, particularly with public parks.
- A strong portfolio of natural style designs.
- Excellent understanding of integrating play spaces within natural landscapes.
- Knowledge and experience in using sustainable and native materials.

This is for my interview portfolio and I am a beginner level of landscape architecture.
However, I do have my own sketch design what to include in there and what I want to express.
