Unit Secretary average salary in the DFW area?

I am interviewing for a US position at a local hospital. I have extensive experience (19+ years) as a medical transcriptionist and in general medical office work. I am wanting to secure this job (though I am sure it will be a big step down in pay) in order to get assistance financially with nursing school and an in-road to a job after graduation as well as to work in a place that will be friendly toward my nursing school schedule.

Does anyone have information on the average pay for a unit secretary in the DFW area so that I go into this interview informed? I get no good comparable results on salary search engines. Thanks!
