When do guys usually give a quote? Do you just give a basic price according to the number of servings they need or do you wait for more details on what they want on the cake?
I'd start with the per serving to give them a base to start with then provide a more detailed quote once you have the design and any specialty cake flavors, etc.
My prices are posted on the website, so they can figure the final price before they even call me. But the official quote is emailed after the consultation appt.
