After spending a summer painting homes, an entrepreneurial 19 year-old Grand Valley State University (MI) student has created a promotional Web site that offers a year's worth of web time at the cost of $1 per minute. At the site, http://www.OneYearForSale,com, buyers can now display their messages on the site's home page by selecting as many minutes as they wish to purchase. "Time is money, so why not sell it?" says student Peter Sauer, who is majoring in business at Grand Valley.
