The alternative solution is to give someone access to your machine, remotely, and enable them to show you how to perform particular actions on your PC. You're in control. Although you give remote access to other users, you can disconnect them at any time and they can't suddenly infect your machine with a virus. You can also prevent access from particular areas of your computer - so files in your 'work' partition are out of bounds to the remote user.
However, if you want to do the demo work, you can choose to help other users and charge a fee. For instance, you could charge someone $40/hour to help someone get to grips with using their email client, as an example. Remember, you don't need to leave your laptop to do this. You simply need a fast Internet connection and hope your remote user also has a fast connection.
