The average salary for a CNA in Orlando is about $12 an hour, Home Healt Aides a dollar or so less. Of course, any service is going to charge more than that because they are the ones who are going to have to do the criminal background checks, check licenses, pay the taxes, and make sure someone will be there on backup in case the CNA/HHA is sick or has an emergency. Generally someone coming twice a day will cost a premium over someone coming just once, and it would rarely be the same "someone."
You can try some of the agencies in Orlando and compare their rates with what the Visiting Nurses Association charges. However, in all frankness, the agencies are usually pretty close together.
I would also suggest calling the local Social Service Agency and see who they use for Medicaid cases. The service(s) they use may be a tad cheaper.
If you were available to supervise, you could look into hiring a nursing school student to come in a couple hours a day. The salary would be about the same, but there wouldn't be the agency's fee. Keeping track of hours, payroll taxes, and Social Security can be a headache though.
Please let me know if you have questions,
