I work with some great 3D-rendering software as SolidWorks, the rendering will look exactly as you want! I just need the measurements of each furniture, the materials and I will start working. As you can see on my profile, I have experience in that kind of projects and renderings. In fact, my biggest project that I made when I was 17 won a contest called "Best investigation projects around Tarragona".
So you can check out a project that I made recently too, the Citröen C4 WRC scale 1:32, with all kind of electronic components.
