Line of Credit transfer question

[Nate Hananger]

Say you have a line of credit for $50K spread over half a dozen credit cards. Most offer 12 months 0% for both purchases and balance transfers.

Then you have an investment opportunity that requires either a certified or cashiers check, or a wire transfer with a time sensitive due date. Personal checks, money orders, traveler's checks or credit card payments are not accepted.  

How do you consolidate the funds quickly and provide them in the form required by the seller?
