Here is a known tactic that big marketers online use-
To create a nice little side income from PPC on a monthly basis, you need to create niche specific blogs that you can run on autopilot. Wordpress is preferred.
Run adsense on the sites and even if an average day brings you less than $2 income, if you multiply that by 30 days you could easily earn $30-$50 with one blog. Then rinse and repeat with other blogs.
If you can do it right, then you should get a nice little side-income that might pay your bills.

Getting someone to join a network is more difficult than selling a product. A lot of people are creating niche sites for a specific purpose of gathering emails and then over the course of a few weeks or months with multiple emails they try to recruit people. Its not a one time in your face type deal, it can be a slow process.
Register at somewhere like Commission Junction if it's a physical product - affiliates go there looking for products. You need to offer decent commissions though.
JoeBucks is good for Health products.
There are loads of places where affiliates are likely to go for products so check on Google.
Post on Forums where affilates hang out - this site, Digital Point forums etc - and make sure to always have a link to your affilate program in your signature.
Why don't you use a Jv partner? Offer a huge commision, and they will help you built your list and make real money! And more and more people will join you too.
