Riverworks Marketing Group wants to design a website—or upgrade an existing site—for a local non-profit—for nothing. Gratis. Free. So they decided to run an on-line competition. Richard Winham talked to the owners, Jackie and Steve Errico, about web marketing and why they decided to donate as much as $10,000 worth of design work to a local non-profit. The deadline to nominate non-profits is January 31.
