You can post your offer to rent on the Rent/Trade Board and see if anyone responds. You would need to make a reservation in the name of the renter. You will have to decide on a payment policy, since the points expire soon, you will probably want payment in advance due to the time restraints.
If these are current points, they could also be transferred to another member- so you should also look at requests for reservations and transfers to see if you can assist someone else with their needs.
Payments may be made in any form you can accept. Many prefer to use a credit card- so PayPal may be an option. Others will pay using a check or money order.
You may want to read the "How to Use This Board" thread at the top of the Rent/Trade Board.
Good luck!
