Hacking together a Google Cardboard demo

Hi
I am new to games development and have been watching a few youtube videos. It looks like UnReal have done all they can to make this easy for those of us without any experience; which is very exciting. Personally, I learn best by doing so now want to dive in rather than watch more videos. I thought the best way to start (given i am no graphic designer) is to purchase a few assets and create a basic world.

I want to put together a google cardboard demo and plan on doing the following:

Buying these assets:
For my environment which people will be able to look around and focus/choose to move around:

or
https://www.unrealengine.com/marketp…antasy-village

For my guide to give instructions (very basic to start - more of an intro):
https://www.unrealengine.com/marketp…ison-dart-frog

Having imported these I want to be able to embed other assets like photos and video into this world.

Is that going to work? Am I missing anything fundamental? I don’t want to buy and then find I can’t achieve this so hoping for a greenlight from someone or else pointers on what else I need to think about before buying anything!

thanks for any help you might be able to offer
