Your vets quite correct, and good for her for not just dismissing it out of hand.
With a bit of planning though it's not too difficult.
I feed a mixture of different meat's, beef, lamb, tripe ( my dog's not keen on chicken so i don't use that ) rabbit, venison, I try for a different meat source each day, to that I add approx 10 % offal ( liver or kidney ) and 10% bone, which can be whole or ground, or even baked and crushed egg shell. Some people add veg every day, I don't, I just use leftovers from my own meals a couple of times a week. I also feed Salmon body oil and some cottage cheese.
If you have a look through the feeding section there will be loads of threads on raw feeding.
There are raw food suppliers who will deliver to your door, depending on who you use, it can work out a good bit cheaper than regular feeding for some, it did for me.
