Building drawings

Shipping container home.

I need 3 designs all will go to the same designer is the first project is done well. I will only post one design now.
First design is of ceiling installed in shipping container.
I need design with dimensions and different angles ..
The shipping container is 40 ft 12 meters long height is 2.9 meters.
inside the shipping container I have brackets installed along the side walls of the shipping container aprox 350 mills from the top inside of the shipping container ceiling.
the ceiling installed is plywood framed 15 mill thick ply frame about 35 mil thick around the edges of the ply.
inside that I have insulation then covered in wrap.

I need the drawings showing the container with brackets and the ply celing installed showing insulation and the dimensions.

I think its an easy project.

Please dont ask me what ceiling is or anything else like that, if you dont understand ceiling this project is not for you.
Thank you
Ideas for the visual style: black an white drawing
Extra notes: The image is not the design that want but a reference to the inside of a shipping container with a ply ceiling
