Someone can create a PoA when they are of sound mind. They can designate any person, multiple persons (even a caregiver) or organization. In my state my mother's PoA documents had to be signed in front of the notary with 2 witnesses who were not family members, plus my mom (the creator) and the PoA (me). The creator and the PoA each have to have a signed, notarized original copy.
I would use a lawyer. POA has to be assigned. The person assigning it needs to be confident to do so. Otherwise, guardianship has to be gotten and its expensive.
I read ur profile. Are u caring for a LO or u have clients. If ur talking about a client than you should not become their POA. Its a conflict of interest. If you are caring for LO then you should have POA.
Having something notarized means only that the Notary has checked ID and that the signature of the person is the signature on the document. Nothing else. My advice for a good POA is see a lawyer. Much depends on this as different entities, banks, realtors want different things on a POA. BE SAFE as this cannot be redone when the person is incapable of making his or her own decisions.
