I need some advice. A friend and co-worker of mine who also does cake has asked me to help her with an upcoming wedding. She wants to bake layers, ice them, and then have me deliver them, finish decorating, and set up the cakes. I have no idea what to charge her to do this. These cakes are HUGE... The brides cake is a 4-tier square cake with a 16-inch base and the grooms is a 3-tier with a 14-inch base. Any advice?
