How much do customised cakes usually cost? My friend was quoted $500 for a Mickey Mouse 2-tier red velvet cake with fondant décor. Is that exp?

my aunt bake cakes.. she can do customize too.. ask ur friend to google on what cake design she want.. i send to her and ask her how much she quote.. plus she use mashmallows as her fondant.. um $200 for 3kg provided the design my aunt can do.. and if too complicated, too much work might be more..
