Why not setup your own affiliate program and allow others to promote your site, earn while doing so and create traffic for you?
It could open up larger sites/companies to sending you traffic as long as it is trackable on your end based on the links and creatives you provide them. Now I don't know if you were looking to payout on any type of leads or free registrations, but I've seen others doing that exact model in order to grow their base.
For any affiliate software needs, I've got what you want
