Hello Johnathan,
the site you reference is running a different theme and has different options, layouts, and styles built in.
Kor has given you a number of examples, but you will need to hire a a designer if you really want to change a theme to make it your own.
You can contact a GD Expert here: https://geodirectoryexperts.com
If you want to make changes to the GD Framework theme you are using, we can definitely help with hiding elements or identifying complex selectors, but we can do this based on the GD theme you are using. Here is the demo that applies to your site: https://wpgeo.directory/gdf/
However, changing one theme to match another is outside of what we can do in support.
