if you have never consolidated before then get quotes from any bank you can think of.
if you have consolidated once then it will be harder. google rightrate to see what you find.
remember the goal of consolidation is not to pay less, but to consolidate many loans into one. Say you have 10 different loans at $2000 each and the minimum payment is $75 on each of them. That is $750 per month. Consolidating will pay them off and give you a new loan of $20,000 and a minimum payment of $200 or whatever depending on the term. If you pay the minimum then you will end up paying more. If you pay more, then you can pay it off very fast and save money.
