If you made a list of the guides that are known to be legit and compared there prices you will find them remarkably similar for a reason. The overhead is a big driver of the price and it is not a cheap biz to get into. By the time you meet all the qualifications, get insurance, pay for fuel, tackle, bait , ice, moorage, safety gear, maintenance, ect. ect. and take what is left over and divide it by the hours you have to put in, you are making a pretty low wage. That is why there are not all that many full time guides. The guy in the add is most certainly not legit because his price does not cover his overhead. I would be really careful going out with guy like that . It amazes me how people balk at the prices of legitimate guides. If a person only goes out 1-3 times a year it is far cheaper and productive to hire good guide than to bear the burden of owning your own boat and all that goes with it. Like most things in life you get what you pay for and this is especially true with guides.
