Thans for the tips everyone. I've been discussing this with another site as well and got some great ideas there too, although most of them do not belive in variety and most don't feed raw either, just more people with different opinions than I.
I thought I had a plan all worked out, sticking to just one food, feeding him seperatly, as soon as he walks away from the dish take it away from him, feeding him any left over food as training treats throughout the day. But after thinking about it I'm not sure if that's what I want to do, even so I'd have to wait a week or two to start it as my b/f is moving in with me this week & my house is a mess. There really isn't room to seperate him until we get things set up & straightened out. That and if I pull the dish up right away I know he will eat even less as he walks away as soon as I put the bowl down.

I think what I am going to do is add a tiny bit of gravy or canned merrick to his food once a day. While still possibly searching for a new diet that he truely loves to eat.
And I will also try hard to get my house & pocket book situated so that I can afford & fit a chest freezer or at least enough money to feed only Kaige all raw again.
