What region/regions are you considering? Most places in Washington do not warrant this type of service but a select few do.
Once you get out and do some scouting you'll see that there aren't too many places in the woods of Washington that require a pack team. Fact of the matter is most places aren't more than a few miles from the nearest Wal Mart! Just the nature of the situation, a whole lot of people in these woods, especially around Elk season. I've yet to find a piece of woods that you couldn't pack out your own from, or at least pack it down to the nearest access point or log road.
