I would look up www.ellsriverblackbearhunting.com , In winter i work in the area that they guide in and i have seen quite a few big moose and lots of wolves. I'm not sure if they guide for moose, but if not ask them who guides moose in that area. In my opinion for big moose you have to get away from the crowds.
Or you could possibly try someone in northern sask like www.shaddlakecabins.com , hunting from a boat is best for moose in my books.
But as always talk to previous clients and find out what the real deal is.
When placing a trail camera don't just look for a well used trail. What you want to do is look for a freshly used trail off by itself that goes from a north facing ridge, thick forest, brushy knob or some other similar bedding area to a food source. Don't forget water sources. Especially in the summer months the deer need water so look for a good trail going down too a creek surrounded by thick cover and place the camera 100 yards up from the water source.
Scent control is very important...
