A lot of people are into simple or rustic cakes so there’s a market. Not everything requires fondant or tortured piping and sugar flowers. Think of the farmhouse weddings with jelly jars and burlap - those brides will be happy with simple swipes of buttercream and their own fresh flowers.
My policy is that cake with one flavor each cake, filling, and frosting with simple buttercream is one price per person and it goes up from there. Additional flavors, fondant, sculpting, or elaborate themes cost extra.
