structural engineering solution for sunroom foundation that can hold 6x6 inch posts that would be supporting 4 LVL beams (2 in x 24 in x 32 ft) where some of the footings would be next to existing house

I am looking to have a structural engineering solution developed for a sunroom foundation that can hold 6x6 inch posts and support 4 LVL beams (2 in x 24 in x 32 ft) where some of the footings would be next to an existing house. The soil condition at the site is clay and there are no existing structures or obstacles that might influence the design. I have a one-week timeline for the completion of this project and it is urgent.
