I am currently going through instructor standardization at Flight Safety Academy in Vero Beach. From what I can tell so far it seems like a great company. They take care of their aircraft very well and have a serious instructor need so you will be flying a lot. There are people here putting on over 100 hours a month easily. Pay is pretty good as well and so are the benefits. They will pay for your CFII and MEI (I believe MEI requires an 8 month contract sign on however).
