To walk a client through and around a project you should create scenes in the locations or in the path you’d like to travel.
You can create scenes manual are you using Mac or PC? The quickest way to create scenes is to use the scene tool 
and choose the semi render option.( if you’re using a low spec computer it’ll slow Sketchup). Then go to the 1st scene (present) and orbit and zoom until you find the next location you’d like have in your animation. Then right click the Present scene ( at the top) and create new. Continue right clicking the following scenes and creating new until you’re happy you’ve created a scene for everything you need to show.
The scenes will export via/to the 3D model viewer button 
OR, you can export the animation as a video. I think it’s: File>export>animation on PC BTW you can change the frame rate and resolution in the settings.
