Schools like Salisbury, Christopher Newport, and Millersville might/should come in at budget. In addition to the suggestions above, look at URI and U Maine…
Maybe a tad past mid atlantic - W Carolina is about $20K ish full pay.
You may want to look at smaller schools do - Juniata or Ursinus College (private LACs), York College of PA - lots of merit to get you to a price - maybe your price.
