Is credit solutions affiliated with debtxs?

I've done tons of personal research as to how I am going to reconcile $50,000 of unsecured CC debt (Citibank, Chase, and United Mileage Plus). I have been enrolled with Credit Solutions of America for the past 3 months and am sooo dissatisfied with their help that I want to get all my money back from them. I have contacted Mezey & Associates which is a Law firm that negotiates debt settlement. Has anyone heard of them? Unlike, Credit Solutions, they seem to have better leverage in negotiating debt with the large creditors and will set up a Trust Fund account towards my debt settlement. Plus, they're certified lawyers who are professional negotiators and not some trained negotiator who knows a little law. I guess, I'm inclined to trust their opinion a lot more. But since the fiasco with Credit Solutions, I want to know what retaining an actual private lawyer will be able to do for me in relation to my debt. Basically, what can hiring a private lawyer for a flat fee do for me in comparison to a debt settlement law firm?
