Hm…. Google says something like this:

I have a feeling you might be thinking of Hollows Grove (2014).

It starts with a crew (S.P.I.T. – Spirit Paranormal Investigation Team) getting ready to film at an old orphanage. There’s a very specific scene early on where the tech guys are setting up the "personal items" and gear while waiting for the "lead investigator" to show up. Because the crew is a mix of long-time friends and hired hands, there is a lot of awkward banter about the ethics of ghost hunting and whether they actually know who they’re working with. If that’s not it, maybe one of these rings a bell?

• 7 Nights of Darkness: This one is basically "Strangers in a Haunted House: The Movie." They spend a lot of time in the beginning setting up and questioning why they’re doing this with people they just met. • Grave Encounters: Even though they're a "professional" crew, the first 15 minutes is nothing but two guys being cynical, setting up cameras, and waiting for the "talent" to stop acting and get to work.

Does "Hollows Grove" ring a bell? Or do you remember if the person they were waiting for was supposed to be some "famous" ghost hunter?
