When do I need to have the cake for cutting?

When do I need to have the cake in time for the event?

How many people do I want to feed from the cake?

What type of cake do I want?

What sort of filling?

Will the cake have to be transported? (after delivery)

What do I want the cake to look like? or what is there about the person the cake is for that would be really special if it was incorporated into a cake?
