I think its a good idea, all-in-all. The only thing you'd need to do really is make sure that each of your programs will actually pay you on each incoming visitor.
What I'm envisioning, basically, is a little shop in a strip mall or something. Someone walks in, fills out their info, and then an employee enters in the leads. You get paid per lead (sounds like $20-60 per lead per company). Then each program responds to the user stating how much they're willing to payday loan the individual, and that money is wired directly to
their bank account.
Is that the formula here? Basically an offline location for you to do lead harvesting?
If that is the case, I think newspaper ads (especially, to be blunt, bi-lingual newspapers) would be effective because the whole reason you'd create an offline location for this is because these people aren't being tapped in to on a regular basis.
The downside is -- can payday loans actually front the money immediately? Can they create a Western Union account to manage the transfer or something like that? I think the strength of payday loan shops is the ability for someone to walk out the door with cash in hand.
