Any online hyperbaric courses out there?

I want to take a hyperbaric course and eventually pursue my certification. I'm already in the position of running a department, but unfortuntely there are no budgeted dollars to help me take a course. I don't have the cash or time right now to travel out of state (PA) for a class. I have found one course online so far, and it costs $1200.00!!! Does anybody know of any other online introductory courses out there? How does one get educated in this field without spending a ton of money?
