It may seem like a strange idea, but have you considered advertising your social marketing?
What I mean is, have you advertised your profiles? You sign up with someone like Enhance Interactive, place a few low cost ads, and start building up your networks. The people who will click through are apt to add you because it costs them nothing, and then you will have even more people to market to.
And, if you registered a domain name to forward through GoDaddy like I suggested, then you may also pick up impressions as opposed to click-thrus. Just make the domain name prominent in the ad, and hopefully at least a few people will type it in manually, or remember to come back and check it when they have more time.
