Hei!
You write that you want 2 products, do you want individual product pages for them or should we do all in one-page? If so, how about product selection > leads immedietly to checkout? Should give you a good user flow :)
By "fully customized background", you just mean that you want options to change the background images -- right?
I've been working with WordPress for years and done a few WooCommerce projects. Feel free to message me questions!
Mvh,
Johan
