The most important thing is to find a production team that listens to you and serves you well. Chemistry, creativity, and capability matter. Outside of those criteria, you need to determine whether you need videography or video production. Typically videography is done by a small one-or-two-person team. Often it involves simpler documentation of events. Video production, on the other hand, can involve more processes (scripting, scouting, casting, etc.) and a larger, often more experienced crew. Video production companies can handle videography, but usually, videographers are not suited to handle full-on video production.
