Reaching out to Pittsburgh

So for my project, I decided to sort out the logistical problems first, to see if I could reach the greater Pittsburgh area, since I have the skills and resources to be able to create a website for it.

I’ve started to look into mass mailers, the University of Pittsburgh has a program for non-profits, so I may be able to get a cheaper price with them.  ->  http://www.pts.pitt.edu/mailserv/bulk/index.html

I also found a local pittsburgh mailer that also has the same kind of program -> http://www.pittsburghmailing.com/casestudies.php

My biggest problem currently is getting access to the database of addresses of Pittsburgh and then how do I distinguish what neighborhoods to send it to?

Once I figure this out, this local information can be paired with the greater website. I was also thinking I could let people download, print and send if they want to mail it in rather than uploading an image or writing a story.

My search for addresses continues!
