Need at least 100 FREE signups to new unique community

I'm looking to get at least 100 unique users to join a new community. Users enjoy 1 gig of secure Virtual Storage (accessible from anywhere), VoIP, SMS, IM, email, Video Mail, Voice Mail, File Sharing, File Transfer, Internet Browser, Contacts Management, Media Player, Games, and more... all in one "dashboard". Upgraded users get 50 gigs of storage and other perks, but upgrading is NOT required. We are trying to help this new community grow. Once enough people have joined in, we are confident it will continue to grow by word of mouth. If you'd like to get more info, please visit [login to view URL] and join for free. You can take a look around and get familiar with what's available. Please include in your bid how long it will take you to get 100 FREE members (no upgrade is required) and what your fee is. Also please tell me how you will keep track of the sign ups you bring in. These new users must use referral name of "FutureNow" for me to be able to validate them. I'm hoping to accomplish these 100 sign ups this month. My budget is very small as these are free members. Users can be from any country, but must be unique users -- not multiple emails belonging to the same IP address. Thanks... OJD
