Welcome to the club, I get 1-2 emails/calls a week regarding this situation. I offer an internship, but I generally only take people who are currently enrolled/accepted or completed a brewing school course. I don't need to take on an intern as far as the workload goes ( I don't complain when I have the extra hands) but I do it to help aspiring professional brewers get some experience and get into the industry. If someone isn't willing to seriously invest their time and money into their career then why should I invest my time in them.
This may sound harsh but there's just too many wannabes out there and many of them don't have a clue. I don't have the time or interest to textbook teach, so they need to be doing that on their own. If they build up a solid base on their courses I find it much easier to walk them through the practical side of the brewing (how to not kill or injury themselves).
For those of you who wish to bash me for only seeking brewing school applicants let me just say that I never graduated from a brewing school like many others in this industry, but I also got into it in 2000. A lot has changed since then, its more competitive and harder (in my opinion) to work your way up and I feel at this time if a brewer wants to make a career and not just a job then having some education can only help.
Just my advice for those looking to get into it in 2012.
As far as the liability goes, have your lawyer draw up a waiver.
