Dh and I take on rescued pets, and our current happy little pack of 6 dogs includes one who has a bite history, quite a few bites actually and all towards children.
We have no children or visiting children. We live in a village where we know nearly everyone, so no-one tries to invade our boy's space - I am more than capable of blocking anyone who tried though!
When we have visitors (which isn't that often as we're a pair of antisocial old gits!) before we let them in to the house our boy trots happily off to his bed in the back of the house with his Kong and one of the other dogs who is nearly blind and gets a bit discombobulated with other people in his space. In the 6 years we've had this dog, he's never once bitten, never escaped out the front door, nor got out the garden gate etc etc. He is still not as relaxed as the others outside, but we take our responsibility very seriously and we look after them all very carefully.
In our situation though @Dogheartbreak, our boy came to us via our vet, as he was going to be PTS. Our vet has known us for years and quite a few of our gang have come to us this way. It could be another option for you to try - see if your vet has a client like us on their books, we do exist!
I only wish we could afford to take on more, but sadly we've decided not to replace any when our current ones die, it costs an absolute fortune. It's not just dogs, we also have a cat, a rabbit, 2 snakes and 2 guinea pigs - nearly all of them were rescued or "Free to a good home" from Gumtree.
Best of luck OP, whatever you decide.
