Thank you!
I understand now. You want to display the custom field names as the title and the content, instead of the default post titles. For that you can use the advanced title and content fields.
I went ahead, and added the customer name as the title, and the address and zip code formatted as the content fields: https://i.imgur.com/KgggPZJ.png
You can change that as you like, add the rest of the fields if needed.
