apushatayid, I have news for you. Your kosher supervision has been in business for a while and everybody who has ever eaten in your home has relied on it.
Also please note, you dont need to be a Rabbi. The din is not “Rav echad neeman bissurim”
Also keep in mind. If food is kosher there is no need for a formal hechsher, and if not all hechsherim in the world won’t help.
