I'm pasting this advice I gave on a recent post...
The single most important thing IN MY opinion is exposure and it's also helpful to have a mortgage guy (or gal) who's a real go-getter (most are) working for you. Call a few up and ask them what they can do to help out a FSBO. You shouldn't need to pay them as they will make money from the mortgage and they want the leads. Most of them will offer to attend open houses and print up brochures for you FOR FREE!

The next thing I would do is advertise teaser rates such as "own this house for $xxx per month" or "$0 down".

The strategy I took was to put out signs like these all over town with the appealing rates. I also had a website for the house and so people can look at it before coming over and taking up my time. The way it should work is the potential buyer calls the mortgage guy and gets prequalified/prescreened. The mortage guy calls you and says "this buyer would be great, show them the house" and then you do. Since the financial mumbo jumbo is intimidating to most new buyers, if all that is streamlined by your mortgage guy, you'll have it in the bag.
This is how it worked when I sold my last house. I bought about $300 in signs and had a buyer in two days. I only showed the house to two people.

My buyer was interested in one thing and one thing only and that was getting the financing deal that was advertised. And he got it.

With the signs, you are reaching so many people who may not even be looking at other homes at the time and they aren't comparing your listing to other listings. They simply pick up the phone or go to the website and you'll have more people calling. I had about 100 calls over the two days the signs where out there.

***Now I think you said you were in TX and if so from what I read that is a strong buyer's market and the price range of your house is obviously not a starter home. I would target people wanting to move up to a nicer home. You can find people that don't think they can afford to move up but it's like showing me an overpriced slice of moist chocolate cake and telling me that it's a bargain and having a closer there to show me how I can pay 3 times as much for the cake but small easy payments. Then I would probably have my cake and eat it too. Find ways to tell as many people as you can about the cake, then have them programmed to believe they need and can afford the cake.
