Obviously, I can't claim that this is guaranteed to bring you an income because it's up to YOU to build and promote the websites.
However, renting space on a website is easy to do once it is already ranking highly on Google. So it speaks for itself that it is, indeed, possible.
Using the training resources on this site to help build your confidence and skills, this task is totally do-able.
Try with one site first and, when it goes well, start another.
I've worked out some earnings in this tutorial as an example but, of course, they are for information only.
Apart from Domain purchase, you could start this business blueprint for free if you're already using the Internet for email, websites and browsing.
I look forward to hearing any results from other WA members.
