If you really don't value your agent's ability and think you can do it better, it's likely best that you 1) interview more to find one that you do trust, 2) go through the listing agent, directly, if you're that comfortable with handling your side on your own, or 3) maybe get your license so you can control your side of negotiations with the proper tools needed (MLS access with agent info, showings, contracts, tax records, uploaded listing docs like surveys, disclosures, broker assistance for questions, etc.).
