Perhaps the only real way to reach free leads is to network with other, more experienced marketers, and perhaps get them to share their lists as a way to get you off the ground. With this, you aren’t really getting free leads as such – more leads at no up-front cost. The other marketers will usually expect that you will send commission to them for the sales that you make.
The reason I started Apache Leads way back in 2003 was that I was a Diamond level distributor for a San Diego based MLM company and had quite a large business. None of my associates had any access to leads, so that's how we got started. The demand for leads grew so fast that I had to focus on getting quality, affordable leads in ever increasing numbers.
