Advertising, Technology, What do you use? 1 Platform all sites...

Hey, Guys, I am a tech nerd, I love using different types of tech to improve my business, I am a big fan of Podio... It is a CRM. I am looking for a platform that can post in multiple locations at one time. I am using Vflyer right now to generate a very good looking ad for my properties, but I am looking for something, or someone who knows how to build something that will post to Zillow, CraigsList, Facebook, Twitter, Realtor.com, Trulia, ETC... 

I know this is possible with some API'S with some websites, and with the proper framework I could probably build it in Podio, but I really don't want to reinvent the wheel if the technology is already out there... 

Please let me know what you are using to get your properties in the most amount of places as possible.
