You can always ask the vendors you’ve already hired on recommendations for other vendors. What you’re looking for is someone you can trust with handling their respective duties in the most professional manner on what is arguably the biggest day of your life. You want a photographer who will capture photographic memories on instinct, a caterer that will be able to prepare and deliver a fantastic meal experience for each of your guests. And you want an entertainer who’s going to be able to take your guests on an incredible celebration throughout the evening. And if you’ve already hired one of those, I’m sure they can recommend others that they’ve worked with in the past. A quality vendor can make quality recommendations.
