Often, what happens is that we run into unscrupulous Internet Marketers (IMs) who have less-than altruistic intentions of extracting money from you rather than helping you to make it. However, this isn't something new. People have been falling for networking marketing, pyramid schemes, and affiliate marketing scams since before the start of the net.
The biggest reason I love recommending Wealthy Affiliate to new affiliate marketers is because it literally provides EVERYTHING you will ever need. You don’t need to buy a domain name in one place then get hosting in another place while you sign up for training at yet another place. Everything you need is in one spot, for one consistent monthly cost. Plus, they don’t just provide the tools, but they give step-by-step training instructions on how to use all the tools properly. If you still don’t understand something, just ask the community or go into live chat, and you could get an answer in literally seconds.
Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs.
