How do I make my garbage disposal work and stop stinking?

My garbage disposal absolutely will not turn on. It doesnt even make any noises when I flip the switch for it to turn on. Also, ground up food particles and water keeps coming up into the sink. My whole house smells horrible, like rotten food. The soonest I can get someone to come out here to fix it is on Monday, but the smell is so bad that I don't know how I will wait. Does anyone know how to fix it or how to make it stop stinking?
