Are you a realtor??
I know that agents are always open to new ways of marketing their business and getting new leads
I sell this small device called gems, and with a gem, you can program it with any 40 character message and anyone with a smartphone within
100-yrds of the gem will receive your ad on their notification screen on their phones.
I used it at a concert to promote my site and I got over 500 clicks to my site
Find out how one agent used them to sell a listing: http://www.promotewithgems.com
