First things First

Priorities are just that.  What you do not learn in a weekend seminar, which is about all people who have jobs can afford-- time wise or financially.  If you can't do an internship, it probably makes sense to find a producer who will allow you just to sit in their office, so you can see what it's all about.  In other words, if this producer doesn't do anything you will know that it's possible that this will happen to you and you will be bored beyond your wildest expectations.  If, however, you like the tasks to be performed and additionally you find the work something you want to do, you will not have wasted your time thinking of theater production as your career of choice.

What do you do once you make that decision.  My suggestion would be to hire a lawyer.  To keep you out of jail and to guide you along the way.  However, find a lawyer that doesn't ever say "we can't do that". Find someone who says, "I'll find a way".  I'm not kidding.  You do not ever want to pay someone the "big bucks" to tell you what you cannot do.  You will also need to find a General Manager (GM), who can help you identify sources of funding as well as handle the budget and all the finances.

The next thing I would suggest is to assess what you have financially, energy wise, and knowledge. 
Never be afraid to ask a question. Even if you have studied how to be a producer, you will not understand until you have produced. In order to do this you will also need to be part of the "theater conversation".  Learn the terms and the tasks... Now take a breath
