Where can I find information on employment, salary, etc. for future teachers (with more details)?

Preferably including these specifics:

-in Missouri

-for elementary teachers and/or special education

-for people with a master's degree, in contrast to a bachelor's

-the next ten or twenty years if possible.

I mostly need to know projected job openings, hiring opportunites, etc.

Graphs or visual depictions would be appreciated, but any information is great.

Thank you!
