I suggest you don't stop interviewing Realtors until you find one that feels good in your gut.
Then sell it yourself. All you have to do is market your house (people have to know its for sale); comply with all disclosure requirements in your marketing and descriptions to prospective buyers (who are prone to sue if you misrepresent stuff); arrange for your own inspection (which you will probably need to accurately represent the condition of your house and to counter potentially unscrupulous buyer's inspectors) to determine the actual condition of stuff like wall, attic, and major appliance wiring, operational conditions of a/c and heat units, termites, dry rot, roof conditions, chimney and fireplace conditions, etc., etc.; be on site whenever prospective buyers show up, or want to show up; negotiate with prospective buyers when they counter-offer and counter-offer again; be on site whenever a buyer's inspector shows up; monitor the buyer's inspector as he performs his inspection to be sure there's no fudging on demanded repairs or alleged conditions; prepare binding option period and escrow contracts; arrange for appropriate escrow; prepare your seller's contract, deed transfers, and real property recordations; arrange for title insurance; and go to work every day in the mean time.
