Do you have a specialized skill that you think is going untapped? Do you think that people would actually pay for your advice on a specific subject? If so, there actually might be a way for you to earn a bit of extra cash, simply by giving advice to other people. At least that is the idea behind MinuteBox.
This interesting site lets you sell your time, or purchase someone else’s. Depending on the role you want to take, you just log in and answer some questions about your area of expertise. You’ll need to build up a reputation before you can start charging a lot for your time, but if you work in a specialized field, it might not take too much time. Conversely, if you need advice, you can search for someone with the right skills, check their references and price, then purchase their time. A very interesting way to get help with something, or sell your time.
