The above post was edited to remove resort specific info, so as not to be construed as offering a Reservation for Rent.
First, of course, you need to post the reservation. Many people accept PayPal for payments. The average rental seems to be about $10 per point, but that is fully negotiable between you and renter.
Once you have reached an agreement on price and method of payment, you call Member Services and change the name on the reservation, and then book your new reservation using cash.
The premise is simple, however, doing so within the 30 day window required by our Rent/Trade board is somewhat problematic. Renting an existing
DVC reservation at 30 days really wasn't designed for the purpose of switching reservations so the owner can stay elsewhere, it was to allow owners a chance to recoup a total loss of points
if they would have needed to cancel the reservation, and risk those points expiring in holding status.
It really is best, at 30 days, to use the reservation yourselves, if you are planning on traveling to WDW anyway.
Renting points for staying at other locations works best by simply offering points, and booking a reservation for the renter, based upon availability. Usually this is done much farther out than 30 days.
