I guess I would start at $2 a slice, than add for all the deco work. Maybe $10-$15 an hour? Just a suggestion.
I can't help with the pricing issue b/c I only bake for my relatives and friends...but that cake looks like it was done with 10 million little stars. Unless piping stars is your favorite thing, I think it would be easier to do the yellow part with a crusting buttercream and then make some dents in it for the holes in the sponge, after it has crusted. My hand is aching just looking at all those little stars in the picture
I only bake for relatives so I dont charge but I would pay atleast $35.00 but then again I don't know about pricing a cake... Good Luck
