I've sold tix on ebay for 9-10 years.
Your best bet is to advertise that who want to buy the rights, and then have the owner transfer to you. The Saints don't have seats rights, and do allow transferring out of the immediate family.
That's the good news. The bad news is that you'll probably pay $3000 just for the rights.
The other good news is that it is a great investment. Regular season games sell for at least 25% over value, and marquee games can often double. I sold my Cowboys tix for 3.5 X face
