Not sure what the local state regulations are, but what about hiring paramedics?
They'll have ACLS and can work under appropriate protocol and (hopefully) be competent in handling any seizures or other medical emergencies. Plus, the $20 an hour will be much more in line with paramedic pay. The part time availability of a paramedic that works 24 hour shifts is excellent. In Missouri, medics are used in the ED, pain management clinics, and some outpatient procedure areas.
I would have loved a part-time low stress gig like this during my paramedic days. Not to mention you're paying my OT rate as a medic for part-time work.
