Personal Shopper for Electronics
The idea is that busy professionals would rather spend their time billing at high hourly rates or with family and friends instead of shopping online. Most "personal shoppers" target those looking for high end clothing. This service would be about finding deals on items like TV's, computers, gaming consoles, sound systems, etc... There are many automated systems that compare prices online, like pricegrabber, google's own service. These services are fine but pale in comparison to the personalized service a human could provide. A personal shopper could read reviews, compare products based on different criteria, find items on Ebay, etc... The price per search would be relatively low.
