Can Anyone suggest an excellent Affiliate Network that caters to Pay-per-lead program?

i am planning to venture into Internet marketing. since i don’t have time to create a product of my own, i would rathre do Affiliate marketing on pay per lead program. I just think that this is easier than pay per sale and more lucrative than pay per click.

What do you think? I am on the right track?

I am an overseas worker away from family so i am looking for additional income so i can go home for good and still have some source of income.
