How to get therapist

So I'm finally ready to make a change in my life and get a therapist because I'm tired of feeling miserable. The only problem is is that I have no idea on how to do it. I've looked up therapists, and have found a few that seem decent but I'm not even sure what to say when I call. Do I just ask to make an appointment or what? Thanks for the help, I really wasn't sure who else or where to ask
