lead generation and selling system

Hi,

Was wondering if any could recommend a plugin or theme for wordpress where I could collect local leads and then sell the leads to companies. As people want 3 quotes I could sell the leads 3 times for example. Also looking for something that is SEO and mobile friendly. I have seen a few WSO that look like they capture the lead but not sure how the notify businesses and sell the leads.

Appreciate any feedback/thoughts.

Vincent
