Air reading questions

Anyone here work with air reading? I have some questions.

Can I choose an age/grade preference?

Can I drop a class if a student is incredibly rude?

I’m coming from a traumatic teaching experience, and I don’t want to deal with behavior and attitude problems for something that will pay me $12. I am a good teacher and I love teaching (especially phonics and reading),but I just don’t have the bandwidth for kids who don’t care to learn right now.
