investigating the design industry

I am interested in changing careers to ID. I have no experience in it and a Bachelors degree in Business and have worked in business for the last several years as an account manager. I do realize that without the training I can not get an ID job, but would still like to get involved on a paid basis to get the full feel of the industry. What recommendation do you have? What jobs are there in the design firms that I can get which would get me close enough to see if this is what I really want to do?
