My 2 cents... (good luck with your little guy)
When he bites, yelp as if you're really hurt and turn your back to him. Refuse to play or interact with him for a few minutes. Repeat as needed.
Also when he's in a bity mood,but hasn't bitten you yet.. give him another option/toy to bite and play with him, with that object. As soon as he bites you, yelp and take yourself away from him.
Good luck. If you're worried about his bond with you, relax yourself, then do some training with him. If you feel yourself getting frustrated or tense, stop the training session. Always end on praise, ask him to do something you know he can..ie sit.
Also be aware of your movements and of those around you. They respond to movement and loud sounds, if you are calm, slower, quieter, it has an effect. Try having massage sessions with him, it'll calm him, it might take time before he lets you hold him, while you massage his shoulders, belly etc. He'll learn, don't get down, if at first he's too wiggly.
He's VERY young and has so much to learn about the world and you. It's very early for you to be giving up too. I'm surprised you'd want to give up so soon. Perhaps consider training classes, once he's had all his shots. Also read up on reward based, training. Training will bond you. Giving up now, is like having a baby, and giving it away, because it's not potty trained at 8 weeks. It's very early for the pup to have learnt how to behave.
You have a lot to learn too, in order to train him to be the best he can be. A well trained dog is a joy to own, a badly trained dog, can be a burden and leave you and him unhappy.
