I am looking to launch a new service (Live-Chat and Live-Call software) for business websites. I am looking for few beta users at the moment. I have a feature-rich control panel where businesses can sign-up. I need good suggestions on how to get beta users (100-150/day) through online marketing. I am getting a new website designed as we speak but even before I launch the service & website I would really like to get some feedback before I start selling it for a price. At the moment I am getting 2-3 sign-ups/ day from what little e-mail marketing that I do currently but I would love to try something substantial and a long-term strategy. PS: I am currently giving out 1 year free license with advanced functionality and unlimited usage to beta users.
