Want your own Million Dollar Homepage? You can have one for $50 with a script from these guys:

The Million Dollar PHP Script allows you to sell advertising space on your website by selling pixels! Pixels are bought in blocks of 100 pixels (10×10), and then arranged on a clickable image map with the advertiser’s link.

I would consider buying this script if I were going to do one of thes pages for sure.
