Trulia does not accept FSBO's. You can post on Craigslist, FSBO.Com and probably many other sites. You can also list with a flat fee company that may use Trulia and then you would be here and on the local MLS.
Finally, I'm going to suggest you reconsider. Some agent's aren't worth their fee, but a great agent is worth more than they get paid. Find a great local agent and you will get more than you expect.
