As owners of DVC we own points as opposed to weeks that some other TSs have. We use the points to "buy" our time spent at WDW DVC resorts. For more info check out the rent/trade FAQ at the top of this forum.
If you decide to rent DVC points - just go to the DVC Rent/Trade Board. Post a thread that tells what you are wanting, or just look for people who are advertising that they have points to rent. All the details of the rental are between you and the person you rent from.
