As PP mentions, you'll want to engage a broker if you're not familiar with the process. David's DVC Rental is probably a good one to start with. They will locate an owner on your behalf that has points for rent. If you are between 7-11 months from your travel dates, they will need to locate an Aulani owner which may take some time. If you are within 7 months of your travel dates, they can use any DVC owner's points but it will be based on resort availability for your travel dates. Most people book between 7-11 months out. If your travel dates are sooner than that, you will need to be flexible on dates, room type, and view.
Other things to be aware of: if they can secure a reservation for you, you will need to pay in full at time of booking. You can't cancel or change anything after you've booked and paid. You will not receive daily housekeeping. You will receive free parking.
