We have all been there, you'll be able to move about eventually. When you start out you don't really have a lot of choice. You might get lucky with a long-term sub position in a desirable district. Or an early retirement they weren't expecting. But for the most part you need to start at a not as great district and then apply to other districts as you gain experience.

I think a lot of districts like teachers with 3 to 6 years of experience. They probably see that as a sweet spot because you don't cost too much yet, but you aren't brand new.
