In these times you wont find a job anywhere with zero dual given. Your best bet would be to find a smaller school (bigger than an FBO, but not a certificate factory) get your ratings with them and unless your a complete idiot they should hopefully hire you at least part time. Zero dual given looks better when they personally trainied you, and know you will use there teaching styles.

Expect to start at around $12-15 an hour and maybe 2 hours a day to start. Than as you have no life and live at the school for the next few months youll hopefully have meet enough students to pull 4 hours a day if your lucky.

Build up your time at that school and once you get some dual given you can jump ship to your dream instructing job (if there is such a thing!)
