Understand that it will be very difficult, and even more unlikely that you will find someone that will be willing or able to take on this dog.
There are a few other options, including sanctuaries, but be aware the most realistic one may be euthanasia.
Usually I would say to hire a behaviorist or a trainer and work with him, but there's kids thrown into the mix here.
In the meantime, feed him in a crate at least.
