I need a personal loan for $3,500....have bad credit.?

I have looked online, and gotten nowhere. My credit score is too low for prosper.com due to a recent bankruptcy (divorce!) and my current AmEx debt (keep reading). I don't have a co-signer. I do have a great job, and the only reason I need this loan is because I was living in an area with an extremely high cost of living (Orange County, CA) and used my corporate AmEx for personal reasons and now have to pay it off or risk losing my job (I have been placed on probation, and get emails about this a couple of times a week). I have since moved (they allowed me to transfer) to Portland, OR, and kept my same CA salary. So, technically I could pay a few hundred a month to pay down the card, but my company wants it completely paid off within the next 60 days. Can anyone help? And, no, I will not fall for the "you send me $ then I send you $" scam.
