I am sorry for your situation. If you really need to sell, even Trulia, as great as it is, it not THE answer. The truth is that in order to sell a home in this economy, it takes professional selling skills.
Let me ask you...If I interviewed with you to sell your home, and I had YOUR track record at selling homes, would you hire me? Meaning would you hire you? Of course not.
So, I recommend a few suggestions:
First, try to sell on your own if you want. On average only about 10% of homes sold are sold without professional representation.
Second, just in case, interview a couple of agents, compare their proposals, then if you need Plan B, you can jump right in.
The biggest problem you have (no offense) is that you do not know what you are doing. My dad said "Confidence is the feeling you have right before you truly understand the situation".
But don't take my word for it. If you would like to interview a top Realtor, I might be able to refer to you one.
