You need to check with your local health department and see if they will clear your home kitchen. Where I live now, Phoenix, this would be illegal. (There's a law on the books prohibiting home-made goods from being sold in/from businesses.) Where I used to live, Santa Fe, would only approve you if you did no personal cooking whatsoever in your home kitchen and everything was stainless steel. (no laminate counters, no wooden cupboards, no wood at all in the kitchen) You also need the delivery vehicle approved, depending on your county's health code. Then, there's always local certification for each person using the kitchen with a food handler's card of some sort. If you are already ServSafe certified, you may be able to use that certification in lieu of a separate test. Pricing is based on the cake & icing itself, props, and other materials. -Plus estimates on time for: multiple meetings, sketches, making special props, sugar flowers, creating cutting diagrams, and delivery. As pointed out above, delivery can take hours all by itself. -And many places will not accept a cake without a cutting diagram. Making these sorts of cakes is expensive and time consuming. If you don't work your cost cards carefully, you can easily wind up in the red on one.
