Mances00, welcome to the gang. I clearly hear your frustration on what must feel like confinement to the never-ever hill. As has been pointed out, you will at some point be begiven a more balanced diet of learners as you improve your own skiing and teaching and as you progress in your cert level. So you should not worry about being permanently assigned to beginners and novices--that "problem," if that's the right word, will solve itself as you progress.
But let's focus on your question about whether ski teaching is the right activity for you. I could not help noticing that the reasons you gave for getting into ski teaching (improve my own skiing and to "talk shop" with other instructors) have a conspicuous and critical omission: a love of teaching.
To take up this work, you must of course love skiing, being around a ski area, talking technique, equipment, ski areas, favorite trails, etc, etc. But, IMO, you must also love teaching--teaching for its own sake. If you love teaching, you will be very glad about this work, as a love of teaching will get you through the bad days as mentioned by Rusty Guy, in a lot better shape than the other stuff.
Yes, you will get a steady diet of people who may not even have seen snow. In fact, at our little area outside Boston, I find myself teaching people who may never learn how to ski. But the satisfaction of getting them into simple wedge maneuvers after an hour and a half is, to me, indelible and addictive. I have a habit of pronouncing, as a person makes their first reasonably stable wedge turn on command, "Hey, now you're a skier!" The look on their faces says Wow!
Again, think it over: "do I really like teaching?" Therein you will find the answer to your question.
