I'd get the electrical done before anything else. You wouldn't want someone tearing up your just painted walls to get access to wiring. Likewise for the floor.
Not to mention that electrical is a safety issue (and you HAVE to have lights) where the floors and walls are aesthetic changes. Safety first.
Get the appliances last. That way, you don't have to worry about getting paint or dust on them OR worry about where you're moving them to while you work on the floor.
