A healthy raw food diet

Hi all,
 
My dog Bob is flying to Australia in less then 10 days.  YAY!!!!!!
Bad news dog food over here runs over $110 and over for a bag of dog food that weighs 30lbs.
With two dogs, one weighing over 100lbs as you can imagine it's going to get very expensive very quick, so I'm looking into some home made raw food diets that would be a good alternative. 
Does anyone have any recipes that they like to use?  Anyone willing to share them?
Any help would be greatly appreciated.
