Self Employed CNA?

it really depends on what exactly you have in mind, and whether you are planning on trying to get reimbursed by medicare/medicaid/private insurance.

you could offer the home care services of a cna, certainly. cnas/home health aides work for themselves all the time. this would most likely be private pay.

as for opening a home health agency, i believe first of all you would need to apply for a certificate of need from the state, and get that approved. while you could, of course, be the owner/founder/administrator of the agency, you would have to employ at least an rn as a supervisor, most likely more than one. medicare does not reimburse for the services of an aide in itself; it will reimburse for "skilled care" (read: rn level), and will sometimes give enough money for that skill to cover aide services as well. but that care given by an aide must be supervised by an rn.

i once worked for a small home health agency. there was an administrator, an rn director of nursing, an rn clinical supervisor, and a clerk that were on staff. then there were several "per diem" staff -- staff that were only paid for the visits they made, rather than an hourly rate. probably 1 aide, 2 lps and 5 or 6 rns. that was the smallest agency i've ever worked for, and even it needed several rns to function.

this would be a very complex undertaking, good luck in what you decide to do.
