Residential Extension Specs Stamp Acquisition

I'm looking for a professional who can get the necessary specs stamp for my residential project (NYS), specifically for an extension. The scope of this project includes:

- Securing a specs stamp for structural plans
- Assisting with the permit application process

Ideal candidates for this project should have experience in residential construction, particularly with extensions, and have the necessary credentials to provide a specs stamp. Familiarity with the permit application process would also be beneficial.
