Which are the best companies to go to for debt help?

I am starting to have to miss some payments each month on the debt that I owe, and I really don’t know what to do. I am wondering if anyone can tell me which are the best companies to go to for debt help so I can get some professional advice on my options. I really don’t want to end up going bankrupt or losing any of my possessions, but I only make so much money each month. I had some unexpected large expenses that caused me to fall behind on my bills. I want to get out of debt and save a bit of money for emergencies so this doesn’t happen again.
