Can I open a crawl space to extend a basement

[James Mercure]

Good morning BP, Is there a company in Nassau county NY or NYS itself that can handle opening a crawl space to extend a basement? I have this Dutch Colonial which has a scrawl space. Since it’s my first time dealing with the “crawl space” situation, are there any companies with a NYS licensed that can do this type of rehab? Thanks in advance for all your help.
