Hello, thank you for your project in freelancer.
Do you have any way to find a stamped engineer to check the design ? Let me know if you have to do it, and will be easy if you find someone.
I have contact in Florida also, maybe I can see a person that can do it for you.
I am interested also to know about your design, let me check and I need to check if it is following the city permit,
Call me if you feel interested,
ThanK you
