I don't know what to expect

Hello Im new to this so Im hoping I do this right but Im looking for someone experienced in this area that could possibly help me. Me and my husband has decided to adopt a boy from the ranges newborn to one years old. We are at the beginning stages and Im very nervous. We will begin the parenting classes in April and I dont know what to expect. But this is my question, after we finish the classes how long will it take for us to do the homestudy and how long after will we know if we are approved to adopt? Also, what kind of things will the agency be looking for during our homestudy? I know that every state does things differently, Im in Florida.
