How to get paid as a family care taker?

My husband is unemployed and is now the care taker for my 78 year old retarded/seizure Uncle who lives with us and requires 24/7 care. The state of FLorida has a program with Medicaid but it only pays $106 / month. My Uncle is on a fixed income and cannot afford to pay out of pocket. I know there must be a program/way to get paid for 8 hours of service even though it's 24/7. There is SOO much info on the web, I was hoping as care takers, someone here could direct us to a program. Many thanks
