In 2009 I did the same thing you are doing - looking for a golfing partner thru the Couples website. I didn't have to worry as there were 10 people going the day I went, and you simply get paired you with some other golfers.
The clubs are in like-new condition. I would plan on spending $80-$100 for the club rentals, cart, caddie & tip.
Make sure you take a few golf balls with you. I think I lost 2 in the round so was glad I took 3 with me.
