You can almost guarantee that no one is going to hire you right out the bat. People don't hire just anybody to show their dogs, they hire proven handlers or people they have known for a while and like their handling style/the way they are with the dogs/etc.
I have been showing for over 12 years, and I am just now getting people asking what I charge, or they are making plans to send dogs to me, I even have a pro handler friend of mine asking me to help show his dogs if there is a conflict, and I am and have never officially apprenticed under a handler, but that is a good direction to go in.
Start going to shows and talk to people, build a friend base, ask about handling classes in the area. You could also join a local dog show club, not sure which is closest to you, but JB might. And that's another person you could talk to about all this, at least he is in FL, and you could meet up with him at a future show.
