Easiest way to create a website like zolo/how it was created?

Hey everyone,

Been looking into zolo.ca. I like the simplicity and user experience for a similar project I'm working on.

Was just wondering if anybody knows how it was built/using what exactly. At first I thought it was entirely custom but I've seen quite a few similar websites built like it. How much would something like that cost?

thanks

It looks like a Bootstrap.
