I have a friend who is in the business in Lexington, KY. He told me to tell you that the best way to get into the business if you have zero experience is through the program at Central Florida Community College. He said it is easier to get a good job in Ocala,FL where he sometimes works than in Lexington, KY, where it is very competitive.
Here is the link to the program. You might want to look into it. I often wished I worked on a farm instead of working in an office in NY.
