Bird dog online

[Mikey Cas]

Hi guys, I have received some interest in a property I have found, and I am trying to bird dog it for a finders fee. Several people have emailed me asking for more information etc. I want to protect myself and the property, and not just give the address, because obviously they can just forget about me and do the deal on their own. Should I ask to meet up with them and sign a contract detailing that if they close on the property I am due x amount of dollars? What is the traditional way a bird dog would approach this?
