Ad Sellers wanted - high comm

We have developed a unique concept where we have a sky-scrapper pixel-ad, which is displayed on our pages. Advertisers can then buy a number of pixels on the site for their site/business. We want someone to help sell these ads, the min purchase price is $100 and your comission is 25% of any sales. The site is a parenting/pregnancy/baby site and there should be a lot of potential advertisers.
