Provide your professional expertise in a liquid market. These days, you can do more than just sell your old books on Amazon and your old handbags on eBay - now you can sell your professional skills on a marketplace. You are no longer limited to searching for a permanent or contract occupation on Web 1.0 occupation sites like Monster or CareerBuilder. The new trend of freelance and project-oriented websites allows people who need help to identify their projects. Freelancers and small businesses then provide bids, ideas, or proposals that these clients can choose from.
