Terraforce Retaining Wall Design

I'm looking for a skilled designer to create a 20-meter vertical or near-vertical retaining wall using Terraforce blocks.

Requirements:
- The wall is needed to hold back soil for a level garden.
- Behind the wall, there will be a garden lawn, one tree, and patio pillars located about 1 to 3 meters away.
- The wall needs to be around 2 meters high.

Ideal skills and experience:
- Experience with Terraforce block design and installation
- Knowledge of landscaping and soil retention
- Ability to create stable structures near existing garden features
