I know there is a good Duck & Potato and also Turkey & Potato diet available from major pet outlets by one of the better makes of complete food. Sorry, can't remember off hand which one. Also Rabbit is an excellent alternative to chicken and lamb.
Would add that dogs with adverse reactions to chicken, lamb and rice diets can also be intolerant of eggs in any form :-( so personally I wouldn't include them in eithe a raw or complete diet.
As another reply said, Prize Choice have a good selection of frozen raw meats etc which I would probably feed with good quality mixer (if you can find one that he tolerates) but I'd definitely add a supplement such as SA37 (either in powder or tablet form).
Good luck with this dog - it must be more difficult trying to place a dog with food problems since a lot of pet owners won't want the hassle of preparing a fresh diet :o(
