Block Delivery Scheduling

Site URL: https://www.fikaflowershop.com/

Hi! I am looking at integrating a calendar into a floral delivery website. I would love to have this as part of the product selection page, for example if the customer is ordering multiple arrangements they can choose what day they would like it sent. I know Squarespace had the date field but this allows the customer to select any date and time vs available day and windows.  Any suggestions on the best way to set this up or integrate acuity. I would like to have 2 window blocks a day, 6 days a week.
