I have horrible credit and need a student loan, fast, how can i get help?

I have horrible credit. I have a private student loan that someone co-signed for me. Her husband saw it on her credit report and wants it off now. So I need to find another lender that will deal with bad credit and get another loan to replace this one and it has to be done quickly. I've already tried to consolidate all my private loans but it's a no go without a co-signer. So it's just this one loan that I need to get changed. Is there a company that deals with bad credit and private student loan consolidation?
