How do I remove 'price' 'add to cart' and 'quantity' from item listings?

Hi there,

I found some helpful threads regarding the topic but it looks like the coding that was suggested isn't working accurately?

I am not very familiar with CSS so I am not quite sure what to do. Essentially I am helping a company with a website that showcases items but rather than having them available for purchase as they want clients to come 'in store' to receive pricing. I'd love an option to add items and select 'request a quote' but right now I am just stumped on removing the pricing.
