I think one can easily make money online for living and without any site is from FIVERR. You need to be creative to provide some unique services in fiverr. If you study the top sellers in fiverr they have made thousands of dollars every month just sitting at home. Now they have opened up some services like video creation services for selling at higher prices not for just $5. So if your really serious in making money online then the best place for you to start is fiverr.
Fiverr is a good source to start.
But theres now need to uniqueness about your service you post on there for demand, since theres so much people on there already.
Not that its bad or anything, just a bit harder. I personally would rather just sell something off ebay and get something cheap from craigslist or goodwill.
You know the beauty of selling in fiverr is no need to struggle for buyers. there are millions of are buyer visiting fiverr website every day so there is no harm in just listing your product or service in fiverr and wait for the order. If you get orders then it is tension fee sales because you didn't spend any money on your product or service marketing. These are completely free of traffic.
Last year I prepared my self around 25 pages guide on one topic (I do not want to disclose the topic). With in a 6 months time, I manage to sold around 240+ copies. This is around 900+ USD I got without putting much effort to find traffic for my product.
