Interesting that you have had all your initial support from friends and family. We have struggled to get our friends and family on board.
I am now trying to do as much social media as I can and learning fast. I have paid also to join backercamp and for a facebook ad to see if that is successful. Backercamp will retweet your tweets which i have heard is key to getting the message out there.
If I have some success in the next few days, I will let you know.
Hope it is going better for you
