Where is a good place to get a private student loan consolidation with low interest rates?

I applied for a private student loan consolidation from Sallie Mae but they said I didnt meet their credit requirements. Which is weird because I have a cosigner who has great credit. I do not know where to turn next or who is a good company to consolidate my loans. I know that I need this to get done ASAP because I have already started making payments of almost 0 a month!! Any advice?

I heatd from someone that student loan consolidation is filing some type od bankrupcy and that if I have all of my loans from the same lender then they are already going to be just one payment. Is this true? I do have a substancial amount of student loan debt and am about to graduate so is it best to consolidate or to leave it alone since I have always borrowed from the same lender? i would really appreciate your help. Thanks in advance!

Did getting a student loan consolidation significantly lower your monthly payments? Did it change your interest rate?
