Modern Photo Gallery iun Sketchup

We are a photo archive looking to put our work online in a virtual gallery and have been looking at ArtPlacer, Artsteps and Kunstmatrix. Each platform has its own advantages and disadvantages, but none of them give us everything we want therefore we are looking to have our own virtual galleries built in Sketchup and then host them on SketchFab or Kuula. I am looking for a modern-looking style gallery with clean walls and spotlighting. The gallery will need an exterior foyer area with a shop, the internal size of the gallery needs to be about 2000 sq ft and can be divided into 3 or 4 sections/rooms and there can also be floating walls that display work. We will also need a cinema room where we can project video (MP4), this room can be about 300 sq ft and near the exit. For visual reference look at the ArtPlace Premium galleries. We will need to be able to change the framed artwork periodically. We will need an editable Sketchup file.
