As others have already said, Trulia doesn't accept FSBO listing submissions. However if you choose to work with either a full service or flat fee broker or agent, he or she can submit your listing to Trulia via the link below.
Trulia will only list properties that are represented by an agent; not for-sale-by -owner.
You can list your home yourself on Zillow.com and Craigslist.com but in order to give your property maximum exposure on the internet; it's best that you work with a real estate agent as then your home will be seen on numerous real estate web sites.
I suggest that you interview a few local agents from different companies to determine who can give you the best marketing exposure and who you feel most comfortable working with.
