Structural engineer needed for wooden trusses

Job ID: 36233595

Budget: $250 – $750 USD

I am building a large post frame barn. I have used metal trusses in the past, this time I am interested in using wooden trusses.
The main barn will be 80' wide by 160' long. So, I will need the 80' wooden trusses engineered.
There will also be a 32' lean-to barn connected to the side of the main barn and a 32' lean-to barn connected to the bottom of the main barn. So, I will also need the lean-to trusses engineered.
