Do any banks outside of the major ones offer 0% APR for fair credit?

If your credit score is 640-660 but you have lots of revolving debt, do you stand a chance of getting a 0% APR Purchase or Balance Transfer card from a regional, store-brand, or no-name bank after being denied by the major ones (e.g., Citi, Capital One, AMEX, BOA, Chase, etc.?)
