What states recognize Florida police certification?

I am currently going thought a police academy in Florida, but I realizes that I may not find work within the state. Some people, that have graduate, said that their was able to get hire in South Carolina with their Florida police certification. Their also say that all of the counties in South Carolina except for one recognize Florida police certification. I understand that each state have different requirements in order to be come a police officer, but I want to know what state will recognize Florida police certification? Also is there an on-line database that I can use to assist me in finding out each state requirements? Thank you for your help!
