People say that knowledge is power.
There was even a TV show with the same title.
But did you know that knowledge is also money? Yes, it is.
You can actually share valuable information with internet users and get paid for it in return.
Ether.
com is probably the most popular website offering this kind of service.
If eBay allows you to sell products, this site is the place to be if you have some personal services to offer.
How does it work:

1. Get your free Ether phone number.
   First, you will need to sign up.
   This is the only way to get an Ether number.
   Since personal contact details are not permitted to be exposed and are kept confidential, this number will be used by potential clients to call you.
   Ether will receive the call and will forward it to if you are available.
   
2. Set your price.
   The good thing about this site is that it lets you set your own price.
   It can be a dollar per minute or $50 per hour.
   You have the freedom to determine your compensation based on your skills and knowledge.
   If you want to have more clients, it is recommended to set an affordable price.
   Most independent contractors in Ether charge customers at $25 per hour on average.
   
3. Set your time.
   Another advantage of working at this site is the flexibility of working hours.
   So, if you have a full-time day job and you only want to take this as part-time job, you have the option to work only during your free hours.
   By setting your available hours, you are informing the clients when they can contact you and when not to call you.
   
4. Promote yourself.
   Once you've learned the ropes to earning money from Ether, the next thing that you need to do is to create a blog and write articles to gain exposure.
   Some people are earning as much as $200 per hour in this website.
   You can do it too but first customers should find you and learn about your offers.
   You can do this by writing ezine articles about your services and linking back to your profile in Ether.
   

Being knowledgeable about something is the first step to earning profits from the internet.
You must be skillful in a particular field.
In this case, you have to be a good adviser.
Selling consultancy services means selling important information which most people don't know about.
