    business_name   : { type: String, required: true }, // business's name

    email           : { type: String, required: true }, // Owner's email

    business_email  : { type: String, required: true }, // business's email

 username        : { type: String, required: true, unique: true },

 password        : { type: String, required: true },

 location        : { type: String, required: true },
