Sidebar Issue

All,
Here is my theme, which is the Entrepeneur (premium theme): https://www.growyourservicebusiness.com/development/

I need a sidebar on the homepage to work with the Nivo and Business templates, which has the sliders that you see on the homepage. Unfortunately the person that I purchased this theme from doesn’t know how to do it and is telling me maybe I can hire someone to customize the homepage to have a sidebar.

He says those to 2 templates are at Full Width and that is why the sidebar don’t show up.

I have tried to find out where to go to change this, but I can’t find it.

Does anyone have any idea of where I can go to make this change so the sidebar will show up with the sliders?

Please help if you can.

Thanks in advance!
