I don't know a good one, but I had a not-great experience with The Credit Counseling Foundation (based in Florida). They charged extra to make your payments electronically and failed to make payments on time several times in the 3 years I used them, negatively impacting my credit rating even more. They did get the interest rates lowered on several cards, but with the up-front payment they required and the additional fees they charged ($35/month service fee), I really don't think they saved me any money.
If you are thinking about trying to do it yourself with a consolidation loan to pay things off, I can highly recommend Prosper.com.
