Creating Contacts with people

[Austin Shireman]

Hello BP, 

I am 19 and recently applied at a real estate brokerage for an agent position. During the interview, the managing broker was worried my age might make my business hard. So he tasked me with coming up with 50 contacts of people I don't know (Name, Phone Number, Address, and Email address), was wondering if anyone on BP had any ideas or advise so people can take me seriously. I plan to go door knocking and maybe trying some social media, but people just don't seem comfortable giving out that kind of info. Any help would be appreciated. Thank you!
