What type of professional should I get to help me manage debt?

I have somehow manage to build up quite a large amount of debt, and I could really use some help to manage this and get rid of it. What type of professional is the best to help a person manage debt like this? Should I get some kind of accountant, or a financial advisor, or should I go to some sort of professional debt management company? I really have no idea what I should do since I have never had this sort of problem before. I want to get help getting rid of my debt and making it so that it is less likely this will happen again.
