Retaining Wall Structural Assessment -- 2

I need a professional to assess the structural integrity of a stone retaining wall. The wall has some visible displacement of stones and I want to ensure it's safe and stable. This is to help me decide whether to buy the property

The wall is in Stirling, Scotland. Only local quotes please.

Key requirements:
- Expertise in evaluating stone structures
- Experience with retaining walls
- Ability to identify potential issues beyond visible damage

Please provide a brief email report with your findings and cost estimate for any recommended repairs.
