Review : The OP shared a straight to the point method to make money selling leads, he doesn't just show you where to get clients and how to get leads but also provide pre made scripts for you to sell.
I've worked on something similar before, and it required me a website and VA's , but seeing that the OP managed to profit from this without a website, team or a big setup is amazing, and hope this will encourage newbies to take action, and if you spent time and efforts learning rhe basics here and trying to brainstorm new ways of generating leads and finding clients to sell to following thee patern shared by the OP , you will be on your way to +$1000/day .
However, there is a point stressed out by some peoples before me here and i'd like to repeat it : This Method Does Require UpFront investment, there are free alternatives for what's shared here, if you're a bit smart to dig a little deeper, but if you're going to sell those Leads, they're just not enough, which i think still Fair, it's a Pay To Play business after all.
