Some of the networks which pay per lead are CJ, Pepperjam, MaxBounty, LinkShare, ShareSale, CPAStorm and others. So you can check them out.Take care.
there are many reputable companies such as copeac,azoogle,hydra,pepperjam but few of them pay affiliates weekly
I know some more interesting programs, please feel free to contact me via PM and I will let you know what I have...
You can get bi-monthly on most networks if you can do $1000.00+ every 2 weeks, which is pretty easy if you have decent traffic.
