While you can't advertise FSBO's on Trulia you can post them on Zillow and Craigslist, in addition to 3rd party sites like ForSaleByOwner.com.
However, if you do ever decide you would like the services of a Real Estate Professional, I would love to have the opportunity sit down with you and discuss how I can generally sell your property much faster & on average for 13% more money than the owner alone :).
Either way best of luck!
