Still, there are opportunities out there, if you know where to look.
Livingston says his company's client companies still have plenty of campaigns running nationwide. Business slowed slightly right before the recession but returned when the economy started going south.
"Consumers are seeking ways to make money, while companies are cutting back on spending for television campaigns and looking for more affordable advertising strategies," Livingston says.
On average, Livingston's clients put about 800 to 1,000 wrapped cars on the road.
Like other similar companies, Free Car Media serves as a matchmaker. Interested consumers register at MyFreeCar.com and then are notified when they meet the criteria a client seeks in potential drivers.
Drivers are paid an average of $700 to $900 per month, with campaigns usually running a few months long. Drivers use their own cars which are fitted with the wrap. "They don't actually get a free car," Livingston says. "But the monthly payment is generally enough to cover their auto expenses like car payment, gas, etc., for the month, so that's where the name comes from."
It doesn't cost anything for drivers to sign up, and Livingston warns people to avoid any sites that do charge a fee.
"There are a lot of unscrupulous companies that want to charge you $20, $30 or more when you can get this information yourself for free. I get calls on a weekly basis from people who are upset because they were scammed," he says. Livingston says that anyone who is directed to his site after paying a fee to another service should demand a refund.
Adding to the confusion, many of the sites -- legitimate and questionable -- have very similar names, often some variation of the words "free" and "car." So it's important to check out the Web site carefully, watching for any mention of fees or membership costs.
Clarke says his company puts a lot of effort into recruiting brand influencers, or drivers who are a perfect fit for the client's target audience.
"Recent engagements have focused on family-oriented and consumer driven advertisers who are generally trying to create awareness within a specific region among active moms with active families," Clarke says, adding that busy soccer moms would make perfect driver candidates for these campaigns. "With active families being such a coveted demographic, incorporating their vehicles is ideal since they're getting tremendous exposure parked in the pick-up line at school, at the Saturday morning soccer games, etc."
There are important criteria for driving candidates. "Background, driving record, employment verification, personal interview, as well as having mandatory minimum auto insurance coverage are part of the vetting process," Clarke says. "We're also looking to incorporate an online personality assessment tool and a short online defensive driving course."
Interested drivers can sign up for opportunities at Drivenmediaonline.com. "We compensate drivers within a range of $300 to $500 per month, with incentives and other engagements that allow them to earn more," Clarke says. "Our typical campaign lasts three to six months, with the time frame and vehicle type being the primary factors for determining their monthly compensation."
