Maybe if you give the reason for needing the money so fast people could give you other solutions. Could you borrow the money from someone in the meantime. I don't think someone with no money at all, who desperately needs a cheque cashed should go down the route of starting an overdraft but we don't have all the circumstances so maybe I'm incorrect.
Forgot to suggest - why don't you go back to the person who wrote the cheque and ask them for some of the money in cash.
