Wooden Shed Engineering Stamp

I need an engineered stamp for a permit on one medium-sized wooden storage shed (100-200 sq ft) and a 20 foot container. Primary issue is the attachment to the ground for hurricane protection. I have engineered plans from the shed manufacturer for the building, but they are generic and not for my exact building. The shed is on top of hard packed base and sandy soil. The container hold down clamps that are bolted to concrete will work as the container is on a 4" slab.

Requirements:
- Provide engineering specifications
- Ensure compliance with local building codes
- Issue an official engineered stamp

Ideal Skills:
- Experience with wooden structures
- Knowledge of local building regulations
- Licensed engineer

Looking for qualified professionals to ensure this shed meets all necessary requirements.
