Structural Calculations for Home

I'm seeking a professional who can perform structural calculations for a residential building. The requirements are

Provide structural calculation for gravity and lateral analysis
and design for this structure. This will encompass the entire structure, from the foundation to the roof.

Due to potential lateral force resisting member layout
incurring a torsion on the roof/ceiling diaphragm, provide
adequate measures to ensure the diaphragm behaves in a
rigid fashion.

Please, include past relevant projects in your proposal.
