Pretty much all CPA networks and affiliate networks i know are free to join, good luck sending your referral link to the guy in PM.i cant tell you what affiliate program to join but find one that doesnt cost anything (and Yes they are out there send me a personal message for help on this) and post a ton of CL ads...Done deal!!!
which ppc networkd did you invest ?1k in 2 days? You need $ to invest in PPC and the most important tool, experience. So practically for a newbie to make 1k in 2 days, can't see this happening with bare hands, regarding making money online. Maybe if you are a girl and decide to go into some porn movie.
