Hi stefano,
At first login to the dashboard -> pages
Create a new page (named it as home) and at the right side there is template, Click on dropdown and select the business template.
Then doing after this create some pages and at the right buttom select the featured image, Create over 3 pages. After doing it go to dashboard -> appearance -> widgets
drag the services widgets to business page sidebar.
Select the three page you have created and under this home page you will be able to implement as in our demo.
