Create a Twel line:
Explain the normal use and set the rates you'll charge for each question posted and response you send. You'll get something like: http://twel.me/domaining
Put your Twel line link on your business card, email, blog, website, social accounts, or simply share it around you. You worth it!
People needing your assistance will start messaging you: You'll earn money just reading and/or responding messages. Each month we'll withdraw your earnings.
