First I will say this... predator hunting *can be* very frustrating and dis-heartening in the beginning. A LOT of effort with little to no reward. Especially when you have to do it all on foot and have to hike-in a ways.
And blowing a call is quite a bit more physical than you'd think it would be. Good exercise. But eventually learn to do the blowing more with your cheek muscles then your diaphragm, that'll help ya to not get all winded out.
To help her not lose interest quickly, explain to her that if hawks and vultures happen to come in to your calling that this is a good sign that you're doing something right.
Start with closed reed calls. They are easy to blow and don't require a lot of skill with your Embouchure.
Get a MOJO motion decoy. The one with the 3 shocked-corded legs is much quicker and easier to setup rapidly, especially if your area doesn't have soft dirt. And makes it easy to set it up upon a Rock if need be for greater height and visibility sometimes.
Mouth calls are inexpensive, loud as heck, and more realistic sounding. Watch a ton of video so your ear can kinda pickup on what you're sorta supposed to sound like when blowing them. Those Primos Randy Anderson how to videos on Youtube are a good place to start.
I've had success with Primos 3rd Degree, but what I don't like about it's design is you *can* blow too hard and cause the reed to "hit-the-wall" and mess-up and the sound either stops coming out or tweaks weird. The Dan Thompson calls.. you can blow as hard as you want and they won't mess up like that.
You'll want to make use of concealment gear.

Sorry about the links not being in-line, I can't seem to access the editing icons for tricking out the post.
You'll want a Predator/Turkey Seat Cushion. They have braced back support. Very helpful at keeping you from getting super sore on your sets.
like this kind, this Beard Buster brand seems to have the thickest cushion part:
EDIT: In general they say to call into the wind... realize the predator will likely attempt to circle in around, unseen to the downwind side of the call/decoy. So you want to setup where that will likely make him have to cross by near where you elect to sit at. Good FOV is VERY important!!! I've had a Bobcat come in to being just 8yds away from me and I didn't know it because of poor choice at where I setup my sit location. When you initially pick a sit location... BEFORE you decide this is the spot.. make sure to crouch down and look around from that lower height your head will be at on the sit. Often you'll find what looked like a good spot ends up not being a good spot because too much stuff blocking your view from down there.
