$800-$1000 a month", I would be embarrassed to pay one of my guides that wage. Now this is in Canada but a standard range is $100-$200 per day, maybe the market is somewhat different than it is in the states. Most guides up here do it part time and for the most part for their own personal enjoyment.
200 a day is a decent wage for a kid just starting out. Here in Montana, folks would kill each other for 200 a day.
In fairness, I don't really know if the guys I've talked to were up the mountain for 30 consective days either. I saw on some of the guide school sites they were quoting 1000 give or take a month.
