Haunting Help Needed...In Pennysylvania

Hi everyone I have someone who needs some confidential help with their home.. children unfortunately are involved in this haunting.
The house I guess is old and it has it's problems major problems.. screaming and photos of spirits in the home and EVPs that just make you chill when you hear them.
And well they have had these problems for months now..
And every time they get an investigative team out there they investigate but never come back with the results and leave the family in the dust.
They have found out that something is demonic in the attic.. possible multiple there and they don't know anything more.. but the place is lively.
The team that was going to come out told them that the sensitives that were coming got ill and they had to cancel as they all ended up in the hospital and so they rescheduled for two weeks from now.. they are going to try to make it sooner.. They have contacted Paranormal State as well but they are booked solid and try to put urgent ones up front...
anyways they are not looking to broadcast this over any air waves and/or media or television or make  movie they just want the stuff gone.
They cannot seem to get anyone to help them to find out what is their home and then they figure out what to do from there..

So what am I asking here?
Does anyone know of anyone a group or anything that they can give me so I can help this family further with some places that may be good not cancel on them and reschedule on them and actually get them the help they need?
And get these creatures out of their home? So they may live in peace?
They are in the Pennsylvania area.  So they need someone either willing to travel and/or in that area.. if you folks know of anyone please PM me and/or post it here.. please..
I figure you guys probably travel some to meetings and such you may know of some groups outside the Maine area..
Thanks all..in advance..

I put this in Paranormal Investigation Groups Outside of Maine -as I just don't know where to put it..and it is outside of maine and need an outside of maine investigator and/or a group that will travel.. I hope someone will have some answers thanks :)
