Sorry about the trouble with Homer. I think he has crossed a boundry actually attacking you for your food. Resource guarding is bad enough but I think this is definately a big step up from that.
I don't think a trainer is the answer. It sounds like you need the help of a PROPERLY QUALIFIED animal behaviourist. I would contact your nearest veterinary college or university and enquire about this, or even your vet could recommend someone qualified with experience.
When I had the behaviour problems with my westie, I phoned the veterinary university and saw a behaviourist who was a vet, she then done a 3year study of wolves in their natural habitat, and finally she taught this subject at university, and believe it or not ,she was cheaper than others who had little or no proper qualifications.
Sorry to rant on, but I know how fond you are of Homer and if you haven't already then I would take him to an expert.
