We,ve had a number of similar discussions about how to break into the business, and they've come from a (perhaps) surprising cross-section of people--young people just starting to look at a career path, and some pushing middle age, who realize that they'd like to make a change in careers.
Do a search and I'm sure you'll find a few of those threads.
In a nutshell, one theme seems to recur in all of them--The fact that you recognize that you have an ambition to do this, combined with your willingness to do some research and ask good questions, will be a big help in getting started. The fact that you have no verifiable experience in the field will be a stumbling block. The experience you get, the things you learn, on the ground, doing the grunt work, pretty much can't be duplicated anywhere else, and is an important ingredient in whatever higher positions you might aspire to.
From the above, it follows that, to find someone who you can convince of your ambition, and your native talent, and get them to give you a chance to show what you're made of, and learn what you can, is a good way to get started in this field.
There may be other paths, but a large number of the people you meet in the field will have followed that one. (And once you see what it's done to them you might decide on law school instead. Worry about getting financing a couple of years down the road...) :wink2
