without giving away to much shane and trying not to steal the thread I'd be interested to know more about your process of selling leads, I know a few of us have sites for solar, electricity, gas, even plumbers etc so if you would care to share that would be great.

The key is providing high quality leads that actually convert for the people buying them.
Another consideration is whether you want to sell the leads for a flat fee per lead, or a share of the revenue for converted leads.
I've used both methods over the years and have found that the revenue share method is the most profitable, but you need to have a lost of trust in the buyer, and you need a buyer that is good at converting!
In terms of finding buyers, it's a bit easier for me since I've been in the insurance industry for 10+ years and have a good network.
It's also much easier to sell leads for something like insurance where a single office can cover all of Australia, as opposed to solar installers or plumbers etc where each provider has a limited service area.
