You can yes. I would pay attention to the statistics put out by the FL Association of Realtors though; people in Florida who list with an agent bring an average 22% higher sale price. The statistics are the stats for a reason. That is quite significant, even if you had to pay a listing agent 3% (if buyer has an agent you will typically be paying that 3% anyway). Sure, some can handle it and get the appropriate price. But then there are 50% of the others who clearly, by law of averages, left money on the table versus what they should have gotten for market value.
The bigger questions are 1) do you know how to run comps on your property (not Zillow estimates as those are not comps) on recent sales to determine what you should list the property at? Listing it too high will result in no interest and too low you will sell fat but leave money on the table. And 2) do you know how to market the property. Sure you can put it in Zillow and Trulia and hope someone sees it. But you are missing the #1 resource buyer agents go to; the MLS.
At the LEAST get yourself a good real estate attorney if you still choose not to use an agent. There are lots of mandatory disclosures and legal agreements that you must be familiar with and can get you involved in lawsuits if not done correctly or something is not properly disclosed.
