Build Bakery Delivery Website

I want a website like [login to view URL] or [login to view URL] where the order part is on the homepage. When a user visits website, they are greeted with some sort of start an order screen so the customer can then select their address via input or using detect location and then proceed to select food items. The main part of the website is the order and delivery section, the user should be able to select their location via auto detect or map drag and drop or via input and then can select, for example, a plain cake and then will be able to add other things on it, it will vary per customer.
