Aggression

My dog is a 4 year old 80 pound husky. He is aggressive towards people when it comes to new toys, food/toys, and a handful of other things. He has went after my boyfriend and trapped him in a room, he gets things off of the counter he in the sink and will go after anyone who goes near him, and a few hours ago he went after me for taking his harness off. He has already been re-homed 5 times and has almost been euthanized. I truly think we are his last chance. I want to try to work with him but is it hard to find a trainer who will work with a husky. I do not want to be afraid if my own dog. Is there any advice on what will help or what I should do with him in order to fix this problem?
