So I had a lady contact me through my facebook page and she told me that she is a cake decorator herself but she's 'old school' and has never worked with gumpaste or fondant. She said that she's going to be making a three tier underwater themed cake for her daughters birthday but she was wondering if I could make some fondant or gumpaste characters for it so she didn't have to buy plastic ones for it. She was asking me if I could make a dolphin, octopus, mermaid, crab and some small fish. I told her I could do it and ship them to her, but I have no clue what I should charge her. What sounds reasonable? Help me please! Thank you!
