I would figure out roughly how much you would need to feed and do a price comparison to the kibble you feed. I think it will probably be more than kibble, but it shouldn't be totally out there.
I tried RAW out of necessity (my dog had a constant upset tummy on kibble) and I will never go back.
If you can price it out, you might find it's not too bad.
I buy sometimes from Big Country Raw (I'm in Canada) and they have a deal sometimes where it's 56 lbs of food for $99. I feed my 70lb female less than 2 lbs a day, so that was about a months worth of prepared food.
If you shop around for deals on whole raw (learn how to balance it) then you will probably be even cheaper.
I don't know anyone who's gone back to kibble after feeding raw.
