Many corporations have a pretty extensive training group in their HR department. Being on onsite training manager may be an option. They have an extensive program in the company I work for.

Another option, since you obviously have a degree, is some type of management development program. The company I work for has one where they hire about 10 recent college graduates (they don't have to be recent graduates, but it tends to work that way with our company), who then do a combination of management training, rotate through the different divisions in our company, spending a couple months in each, are mentored by our executive management team, and at the end of their 2 year program most get permanent jobs with the company, but have no obligation to stay. They are paid quite well as full time workers, with all the benefits any other full time workers get. It's a very successful program and a lot of corporations have them.

Just a couple of ideas to add to some of the other ideas that have been posted.
