Hi, Alan. In addition to the model, you are also asking for rendering. If you really require realistic rendering this will need to be done in a rendering application external to SketchUp (using the SketchUp model or an export of it.)
SketchUp is a modeler not a photoreal renderer. But SketchUp can do “sketchy” style non-photoreal renders.
Most responders we would hope will give you links to see examples of their work.
To look at what some of the community has done, you can browse the Gallery category.
And you can even search it (once in the category) by using the search menu (magnifying glass icon - top right).
Try searching on the word “render”.
As an example see the posted renders in this Gallery thread …
Here is another …
I think you get the idea …
