This is an important question. First, I recommend searching for professional bakers in your area. Then look check out their websites and determine if they have cakes similar to what you want; this is vital. You need to pick someone who has the skills required to bake the cake you want. Let me provide an example. I have a friend who makes spectacular cakes, but she never uses fondant in her creations due to the taste. I would hire her for a delicious cake, but not if I wanted a spectacular cake sculpture. I'd look for a baker who specializes in fondant and uniquely shaped cakes. Once you narrow down the list, contact each qualified person and see if they are able and willing to create the type of cake you desire.
