credit card

Hello folks... im after some advice for my brother. Hes after a credit card with about £5000 limit hes gonna pay off whats left from a loan which is £1500 and use the rest of the balance to pay some bills this month due to a cash flow problem with his business.
Next month he will clear the balance or at least most of it. Would a 0% balance transfer card be ok to clear a bank loan? And which would be the best card to use?

Thanks in advance!!!
