Structural Engineer recommendations needed

We just bought a semi-detached 2-story house, and there is a sag in the same spot of both floors, with what I think is a corresponding crack in the outside wall. We need someone to figure out what the issue is an if this has to be fixed before the more superficial parts of the renovation begin. Our architect recommended that we get an engineer. We had the house inspected, but the inspector could only make an educated guess as to what’s causing the sagging. Could someone recommend an engineer who could tell us definitively what’s causing this? (Someone to actually open up the floors or the ceiling to figure this thing out? The house needs complete reno anyway.)

In addition, we need advise about which walls are load-bearing.

We appreciate any recommendations!
