If you need a Realtor you may call me at 646 251 9618
Since you are a "property manager" you can list your apartment for rent right here on the Trulia site. Click on the "Rent" tab on the banner at the top of the page. A drop down menu will appear with a tab "Free List A Property". Here is where you can input your rental listing.
I also suggest posting it on Craiglist.com.
Good luck and Happy New Year!
