Absolutely, yes you can make as much or as little income from affiliate marketing as you need or want.
When I started online that was my easiest method of getting a check in the email.
I signed up for a free account with Clickbank and looked for affiliate programs that:
- Interest me
- Paid a high commission
Then I would rewrite the marketing materials from those programs and post the information
as blog post, etc.
You must be sure to check in with the program (s) to make your affiliate links are working.
