A "citizen marketer" is offering him/herself on eBay.
For an entire year, this person promises to "…preach the sermon that your product is the be-all, end-all, one of a kind, can’t live without product of the century. This campaign will include written ads, blog entries and a video ad to be displayed on the Internet or for broadcast on television. These strategies will ensure your company and product are never far from the thoughts of consumers."
The catch is: this person wants to be paid.
