I need a loft space modelled in Skethcup

Hi, I am working on an interior design project and need the shell of the space modelled for me. I have the section, elevations and the floor plan of the space for reference. need it to be modelled on Sketchup so I can work on it later on.
All I need;
- walls
- windows
- doors
- vaulted ceiling
- stairs
to be modelled.

I need this model as soon as possible so please only apply if you can deliver the model within 24 hours.
