I've been asked to make a 3d hello kitty all cake( no treats). sitting or standing, any ideas on how to make it and how much to charge? please

I did one not too long ago (in my photos). I just used a wondermold pan for bottom and ball pan for head. Sit head on cake board and dowel through wondermold. For the arms and legs, I actually used cupcakes. Hope that helps.

P.S. I used spaghetti colored black with edible pen for whiskers.
