I suggest you give Traffic Junky a look and trial. It can be great for targeted GEO Ads. The learning curve isn't too bad. Just make an ad to whatever size of the network you want to advertise on and monitor the results.
Juicy Ads is another way to get traffic to C4S. Basically you buy adspace for an allotted amount of time on websites that might be in your niche.
Here are aff links to both sites.

Hit me up, I might have a few Reddit techniques for you to try.
