deck plans for permiting

I'm looking to build a raised deck with size dimension 450 sq ft. I already have a design in mind and need help with plans for permitting from an experienced professional. The project involves creating detailed plans for a staircase, handrail, structural support and other specifics associated with a raised deck. I'm hoping to find someone with expertise in building decks with a focus on engineering, calculations and inspection of all components. If you have experience producing detailed plans for decks of this size and can help provide necessary documents required for permitting, please get in touch. Thanks.
