Where can I find information on student loan consolidation, both private and federal?

I have about $50,000 in student loan debt multiple student loans. About half of my debt comes from federal loans (both subsidized and unsubsidized), and the other half is from two separate, private lenders. I graduate in May, but I can't find information on consolidation. I already have a full time job after I graduate, but making multiple minimum payments to different lenders seems a little ridiculous.

Does anybody have information on how I can consolidate my loans into one loan? Most consolidation programs only let you consolidate your federal loans. Like most recent college graduates, I won't have any collateral to take out a "conventional" loan from a local bank. Also, I would like to do this from a company that will keep the loan classified as "student loan debt" to take advantage of the tax benefits.

Thanks for any advice you can offer.

** I am aware of the pros and cons of loan consolidation. I would like to explore this option for having the convenience of one payment as well as having the option of a lower monthly payment

No, there is not one lender who could or would take on that mix of student loans. Consolidate the Federal loans and leave the private ones as is.
