Second, I can understand your concern about hiring an inexperienced and unethical Realtor. All I can tell you is to interview a few agents and go with your gut. You want to make sure they have listed, marketed & sold estates before. Ask for proof/references!
All that said, I recently sold 2 estates and would be happy to interview with you on the phone and provide you with references.
