you want bengladeshi kids. they are used widely as slaves throughout the middle east, so they have good recommendations. they eat only lentils and peas so are cheap to feed, and generally smaller than american kids so you dont even have to buy that much of the food. Moreover they can be trained to herd camels, speak english and do a lot of sewing, so you know they are adaptable. At less than 100 dollars US a slave, its a great deal
