what type of atty do I need & where can I find one to represent my mom (86 yrs) who contracted sepsis in a rehab facility (Randolph Co, NC)

My mom had surgery and was required to go to a rehab facility post op and within 2 weeks she had to undergo major surgery to cut out some or all the infection due to neglect. My cousin asked that the dirty bandage be changed and the surgeon is a witness along with attending nurse @ Chatham Co, NC hospital that my mom's wound got infected due to not changing bandage, poor hygiene etc and the facility did not notice the symptoms. She was seen on a Wed t have sutures removed, I did not visit on Thurs & Fri I witnesses mental confusion, shakiness from chills etc & at the hospital her blood pressure & oxygen levels dropped and bladder / kidney was out of whack according to the nurse.
