Promote lead automation for customer base

How do I get a customer list in 3 days that will be interested in signing up for a free beta test that will get them a customer base with lead automation? Hi I’m just starting without much money and want to do a prelaunch to get people on an email wait-list or they join social media pages so they will sign up for the free beta test in 3 days and maybe stay on as customers. The beta will get them access to the lead automation software and it can get them a customer base. Any suggestions?
