Are you wanting to make it yourself or get it from a bakery? I made one for a friend's birthday using a square pan and a round pan and ice cream cones. If you want to make it yourself, there is a great website with tons of pictures and forums to ask questions of some very talented people as well as recipes for moist cakes and yummy icings. It's www.cakecentral.com and it's free to join. If your wanting to buy one, I'd check with some local bakeries. They will be more willing to cusomize a cake for you. Just keep in mind it'll be costly. If you make it yourself, it'll take a lot of time, but will be a fraction of the cost.
