Things to look for:
Your tutor should dress professionally. You want a tutor that takes this job seriously and promotes themselves as a professional.
Your tutor should be friendly as well as professional. You don't want someone who shows no personality. The learner will respond better to someone who is friendly and caring. On the other hand, you don't want someone so friendly and relaxed they are like another child. The tutor needs to demonstrate an ability to take charge when needed.
Your tutor needs to ask questions. Is the tutor curious about the learner? Does the tutor want information about the learner's needs before beginning lessons? Questions asked by the tutor will demonstrate how interested the tutor is in being prepared to teach and tutor and how well the tutor knows what information would be needed (would demonstrate application of experience and education).
On-the-spot responses. While it's great that the tutor can answer questions in an e-mail, can this tutor answer questions on-the-go? A good tutor needs to be able to immediately respond appropriately during lessons. Tutoring happens now! Not tonight, after the tutor e-mails you.
