There is a rawfeeding group on yahoo that I found to be very helpful when starting out (and even now!).

You'll find explanations on the amount to feed, how to incorporate organ meat, etc. on this website and of course you can search the archives to see how others began.
How much to feed depends on the weight of your dog (generally 2-4% of their adult weight). My adult yorkie/poodle mix weighs a little under 7 pounds which is her desired weight. So I convert that to ounces, 112 oz. and then figure out what is 3% of that which is 3.36 oz. So I feed a total of 3-4 ounces of meat a day- and I feed once in the morning and once in the evening. I don't worry if I go over some, because I can adjust a boneless portion easily. I used an old post office scale my husband's office was getting rid of to weigh on in the beginning til I got used to eyeballing a 1- 2 oz. piece of meat!
I feed venison, chicken thighs/legs, boneless breast, pork ribs, calf liver (a tiny amount a few times a week), chicken heart, lamb if it is on sale, etc.
Venison is my main staple. Since deer hunting season is coming up in Virginia, I've already put the word out for my friends who hunt to save me some meat, so that is a way to save on food costs.
There are a lot of raw feeders on Yorkie-talk who helped me tremendously when I started out. We added another yorkie (Biewer this time) to our family and he is now about 17 weeks. I had forgotten how much fun it was to introduce a puppy to raw feeding.
Best of luck and I hope a lot of others who have much more experience than I do will chime in.
