interior finishes, colour pallet and roof Concept 3D Visualizations

I have a 2,200 sq ft office to build on the second floor of a industrial steel shed building. building has a sloped metal roof and so for the office false beiling below the metal roof, i want to skip plain flat false ceiling for this office (or regular grid false ceiling) and want to test several false ceiling options - i need realistic 3D views of the office with furniture and suggested surface that compare different combinations of flat and sloped roofs or use my suggested roof option. need views with all furniture and textures shown as per my sample render

You are free to work in AutoCAD, SketchUp, Revit or any tool you are comfortable with—as long as the final images are clear, well-lit and high enough resolution as shown in the sample render.

please advise time needed, what you will supply and how many and what you cannot share
