I have only a little credit history and my parents credit is horrible, but I desperately need a private student loan. What company is most likely to qualify me?

I currently have no credit history, and no available co-signer for a private student loan. I have exhausted my availability of government sponsered Stafford loans and Pell grants. I need a private loan in the amount of around 2000 dollars to supplement the remainder of my tuition that will be paid out-of-pocket through working on nights and weekends in two jobs.
