Foundation & Roof/Truss Plans -- 2

Looking for structural engineering and architect skills. I have CAD plans for 2 homes that were originally 2 story colonial design. They have been redesigned into ranch style eliminating the upper floor. I am seeking a structural engineer to update the foundation plans for the lighter load. Additionally, seeking to have roof/truss plans created for each of the 2 homes as well. I have completed CAD drawings and original foundation plans...just need truss plan and updated foundation plan. Plans must meet Ohio, USA code for structural;/foundation and roof/truss

Attached are the new home ranch plans in PDF and CAD files. Also attached are the original colonial style foundation plans as a reference.
