How can I add a 'request a quote' option for product buyers?

Hi,

My client sells ceiling lamps on Her Shopify store. She wants to offer the lamp buyer the opportunity to request a quote for installation - when Her customer is buying.

This one came to my mind at first: “Radio button” which ask something like: “Do you want installation?” and options: “Yes” & “No”

What would be the best way to do that option?
