Backyard Deck And Pergola

I have an existing backyard deck that I want to demolish and redesign. I want to expand one side of the deck and have a pergola on the other. I also want to do minor site work to the backyard (removing part of concrete flooring and minor grading).
I have drawn preliminary plans on Revit and AutoCAD, but I need a licensed engineer to verify my structural design and to sign /seal the building permit plans. Being able to show me detailed renderings would be a plus.
