Cake

I was looking for a wedding cake for September 6, 2008 (Saturday) for my wedding that is taking place in Long Island. I have about 200 people and would like to know what your prices for the wedding cake are. \I was looking for white cake with some pearl dots on them. I want it to look like 4-5 boxes one on top of the other going in different directions, with a big bow on top. I would like it made out of fondant and sponge with chocolate and vanilla custard.

Please FM how much that would cost. TIA
