Well, getting the icons is not the problem. I am able to make it look nice on my desktop, but not on mobile. If you check the website on mobile you'll see that the trust badges are below each other instead of next to each other. I don't think it's possible to do that without an app or change the code.
Yes indeed you are right, you would need to create or hire someone to do a custom Section for that as the closest section I've seen on the "Editions" theme is the 2x2 Promotions Section.
Let me know if you need further assistance on that, I can assist on the above. Cheers!
