Which ISA are you using?
Also does anyone know how quickly you can withdraw your money from an ISA?
Don't have any suggestions for you, but you could try looking on the moneysavingexpert.com forums for the current best deal. Internet accounts can take from 2-5 days for the withdrawl to appear in your linked current account, if you have an account where it can be managed in a bank branch, then you can walk in and make an immediate withdrawl.
Taking money out of an ISA is discouraged as you cannot put it back in, but you already knew that...
