As you can see the pay varies d/t location and experience. I am in the field 26 years now. I started as an assistant making $5 an hr. When I started as director I believe it was at $8 an hr. I am ADC certified for 24 years. I now make 48,000. Around $22.25 an hr.
Don't be afraid to ask for what you want. You can always come down if you want the job.
