They offer a totally free, 120-hour PDC course online. It was recommended by a very knowledgeable permie friend. I'm not sure what time restrictions and deadlines might be involved as I haven't had time to get started between school and work but am eagerly anticipating the end of school so that I can dive right in.
Hope this helps.
