Build me a one-page webshop

I need a simple one-page webshop.
Infobox on the top, and products below. Must be able to add and remove products through the dashboard.
Prodducts will have a image at the top and some text below.

Here are some references projects, I basically want it to look like this..:

https://iwanna.atshop.io
https://hitvision.atshop.io/
https://inoces.atshop.io/

I'm open to adding to some color or other gfx to make it a bit 'fresher'.
