Remove These Modules

[614wireless]

I am trying to remove some modules from the website. I cannot find what they are called. The link is 614wireless.com and I am trying to remove our brands, about us, and the big picture in the middle that says new sound with the text "Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical." I included a picture to show if you cannot access the website.

Hard to tell since it's a custom template. Template Monster?
Check modules->positions and the displayHome hook, for the big image and brands. Unless the theme uses custom hooks, they should be there.

The footer one seems to be called "about us block" or something like that, given the code.

Otherwise, try asking the theme's support
