I would call a couple CFP's and tell them on the phone what you are looking for. Some will accomodate this and charge an appropriate fee for the service. Keep in mind the fee per hour may be very high in order to make it worth their time for a one time fee. I'm a CPA and don't accept annual clients or fee per hour consulting, not because I want to charge people for services they don't need, but because its not time efficient and a little more of a hassle.
For instance, instead of billing at $200/hr, it might be $400/hr.
