Can anyone recommend LEGIT Credit Card Consolidation Companies???

FH and I are looking to consolidate his credit cards into 1 payment.

Can anyone recommend a reputable and legitimate Credit Card Consolidation company that will do large balances and NOT charge and INSANE APR.

We had looked into a credit card w/ MBNA, but only would give us $25K limit and it was going to be at 21%.

TIA!
