Find the farthest place away from his cage where is comfortable and sit in a chair there. As he becomes more comfortable, move the chair slowly until you are right up next to his cage and he is comfortable. Keep in mind quakers CAN be cage territorial, not to say that every single one is.
Once you can sit right by his cage, proceed with a stick in your hand, offer it to him as a perch inside his cage. If he is scared of it, leave it by his cage for a bit, and then at the bottom of his cage. Once he steps on reliably, begin to take him out.
From there, when he is out, offer him treats! Once he is comfortable taking treats from your hand outside the cage, ask him to step up (onto your finger this time)and reward him for doing so! Continue just spending time with him and talking to him outside the cage as well as in!
You can also try giving treats through the bars before proceeding to stepping onto a stick. I couldn't do this with my quaker because she is too aggressive in her cage (we are working on it).
It might take days, weeks, or months! I have had Starry 3 weeks today and she is just now beginning to actually enjoy me (a little too much now, I can't leave the room without a bird flying to land on my hand

).
Just keep in mind that these little guys are full of personality and will let you know what is right and wrong. If Starry doesn't like somebody, she shows it! If she doesn't want to be scritched right then, you better move! But at the same time when she is in the right mood, her cuddles are the best!
Good luck with your new baby! Do you have any pictures? What's his name?
