As Randy said, why not just give/send it out with the quote? If the quote is given in person, then just print it out and hand it to them. If the quote is given online, the disclosure can be part of the online process (with appropriate consent). If the quote is given over the phone, mail it out.
But technically the notice only has to be given to those who actually request an extension of credit, so if it's sent when the application is received, that should be fine. For those who never actually submit an application, it's not required to be sent.
