Even with no "product"
you can get paid.

Making money online used to pretty much demand that you have your own glossy web site, unique products to sell and some marketing brains. But a new generation of dot coms have appeared that will pay you for services you supply - without you first becoming a web designer or a marketing guru.

ELance - This one's name gives it away. Copywriters, Bloggers, Programmers, Coders, Web Designers, Writers, Editors, can look for freelance opportunities here.

ClicknWork  - Get paid $5-$150 per hour for simply doing freelance work on a per assignment basis. You will have to pass a test to get in.  

H3.com - Get paid to fill jobs. Commissions range from $50-$5,000 per transaction. It all depends on how difficult the job is to fill and how desperate the hiring company is. It is a case of connecting people with posts.

Indeed.com - Add their job board to your site. They then post jobs on your site based on the geographic location of visitors and the position types you select. This is an interesting way to make some extra bucks.

Tutor.com - If you are a brainiac or a natural teacher, you can get paid to tutor people like me online. Help a student in Algebra, Geology, Excel or whatever. 

InnerSell - If you have a customer that wants to buy something you cannot sell, you can sell the lead here. It's free and it's money for free.

Ether - Are you are an expert on something? Do you know XP, Vista, wireless networks, counselling or whatever? Ether connects you with people who pay you to talk about it in a one-on-one setting. You set your rates. If you want to charge $250/hr, that's fine. Advertising yourself is up to you. So ideally you will want to have a blog or site already established, but it is not required. Get paid to help people.
