You can make extra cash as a brand ambassador if you’re willing to hand out flyers on the street, dress as a mascot or help promote a company in other ways. Or you could do similar work as part of an event marketing team.
You can register with a promotional talent or event staffing agency, such as Street Team Promotion or Across the Nation, to be notified of jobs in your area. Several recent job listings for events on Across the Nation’s Facebook page were paying $15 to $20 per hour.
