Not to say that you won't be able to find qualified people on here, but you might find it much easier to manage this type of operation by doing it through an affiliate network. There's a million and one affiliate networks looking for quality merchants who want to buy qualified leads. Using a reputable network will not only make it easier to manage by A LOT, but it will also provide you with quality assurance to make sure that the leads you're being sold aren't worthless.
I've done this both ways and, even though I did it on a fairly small scale, I can tell you that doing it through an affiliate network is much better. You'll get more volume, quality and the network staff will manage almost everything for you.
