You must have patience. I had a Lutino cockatiel named Sunny as a child and had the hardest time taming her. She bit me many times before she would trust me to hold her. I was told by the handler to pick her up intially with a gloved hand and pet her with the other hand to get her used to touch and then gradually remove the glove. I never used the glove I was afraid it would scare her. You might try it if you do not want to get bit. But patience, patience, patience is the key.
