I agree with Dunes. Get it on the MLS! I am a REALTOR, otherwise known as a FSBO's enemy, but that doesn't have to be the case! I have a lot of clients/prospects that MUST move but can barely break even on their home. Go ahead and try it yourself and be willing to pay agents that bring the buyers to you. Being a FSBO is a lot of work and sometimes it's hard without another perspective on your property, but sometimes, it's necessary.
Don't forget to do a Seller's Disclosure (and disclose EVERYTHING you know about the property to keep yourself safe).
Here's the order that I usually take when listing a property:
Find Comps/Decide on a price (FSBO's are popular for being largely under priced or largely overpriced so this is key!)
Pull it up on the appraisal district for important information like tax appraised square footage and unexempt tax amount. (Put this info in your flier/online)
Take pictures and measurements of the rooms
Put a sign in the yard
Market, Market, Market
----put it in the paper, hold an open house, send out postcards to neighbors/neighborhoods one step below my level (example, if you're in an established neighborhood full of families and retirees, send postcards to a first time home owner type neighborhood), trulia, zillow, facebook, landsoftexas.com, MLS, OTHER REALTORS
And then keep reevaluating what you're doing. Price? Marketing? Etc...
If you get in over your head, go ahead and hire a good REALTOR.
