Jim Morris (P.E.) that works at
Jendusa Design and Engineering out of Hartland is certified by Wisconsin.
I had him provide me structural repair plans for a permit to address a sagging floor (undersized main beam/column/footing/joists).
ETA comment on costing: I tried looking up what the cost was (mailed invoice, no email searchable record), I looked at my bank statements around that time and believe it cost $600 to analyze the house, take measurements, go up in the attic to understand the odd construction layout with the building, and generate final calculations and write the summary and repair report.
I had him come back to look at a sagging beam over the garage entrance (living room above it) and to design a flitch plate beam to replace the existing undersized beam. I believe that cost was around $275-$300
ETA2 8/28: No problem. (and corrected typo, right=write)
