Here's a good idea. Help vacation home owners to rent their properties.

I just rented a cabin using vrbo.com. Each rental has a pop up calendar to show the available dates. VRBO charges the owner $179/year. That's a good deal for the owner and VRBO.

"Back in 1995, we created our first web page (to advertise our Breckenridge Ski condo). Today, VRBO is the largest and most popular Vacation Rental listing service on the Internet with tens of thousands of properties all over the world."
