I know I'm probably non direct competition to what Ryan is offering and I have NO idea what quality of service he can provide. But...

Google Analytics and Ad-works are a decent strategy. As long as you have a decent CRM collecting the info, functional website and good landing pages you can drive a lot of traffic to your site and have merchant's plug in info. Does cost money but if setup right you can generate decent leads.
Overtime Google will learn what a "qualified lead" would be too.
