Where can I sell leads?

[infernostudio]

I am currently developing a few websites which are getting some traffic targeted towards credit cards, surgery, health, real-estate and mortgages.

I am wondering if there any companies out there buying Canadian leads?
This company would need some kind of plug-in which I can integrate on my website and make it look like its my own brand.

I know that leadpile.com has something like this but I am not sure if its Canadian based and if they have anything I can integrate on my websites.

Thanks!
