Highly intelligent African grey parrot available for adoption

Well, I'm not very good at writing ads, but I'll explain the situation as it is. This African grey parrot has lived with me for about five years, and honestly, he's one of the most intelligent animals I've ever had. At first, he was very quiet, but over time he started copying sounds from the house. Now he imitates the telephone ring and sometimes even the sound of the microwave. In the mornings, when he hears movement in the kitchen, he starts making noises as if he's greeting me. He usually spends several hours outside his cage walking around the table or sitting in a chair near where I'm working. He's not aggressive, but he needs someone patient because these birds are very sensitive and need daily interaction. The reason for adopting him is that my job now requires constant travel, and I feel like I can't dedicate the time he deserves.
