Are you kidding, they barely do anything that smacks of being legitimate research on Psychics let alone ghosts, UFOs, OBE/NDE, etc.
While you may have one or two members of the JREF or similar groups willing to take a peek you have to understand up front that they come in with their mind's already made up even if they can't give you a valid and logical explanation on the spot. As far as they are concerned you don't have ghosts -- PERIOD! Even if Casper were to jump out and cause them to lose considerable bodily waste all over your floor after oozing out of the trousers, they will deny that a genuine haunting exists.
Find a Haunt Investigation team that is composed of legit researchers; most such teams will have more than a few real scientists involved that are "open minded" and true skeptics vs. cynics. They rarely have more than two "Psychics" or "Sensitives" along with a couple of simply curious/concerned folk and at least one technical person to support all the camera and information gathering equipment used in their studies. They will come back several times to double check findings; rarely claiming a solid conclusion from a single visit, just probabilities. What's most important is that they will look for natural phenomena that could explain your situation; everything from being close to power-lines to underground streams and even heavy quartz deposits in your region. . . there's a number of very natural explanations you must be open to. . . but understand that such things are generally offered as a "likely cause" or even a "catalyst" behind the phenomena you are experiencing.
The other things to consider is whether you are dealing with a genuine haunt or a poltergeist?
If you have children in your life that are coming into puberty chances are strong that the latter is the case and the situation will come to an end within a few months, rarely lasting more than two years. No matter what you do when it comes to relocating, the sense of haunting will follow until that child has move-on biologically and psychically to the next stage of life. Children with strong imaginations and a sensitivity to the environment are the most typical profile for such things.
Haunts are location or item based; the entity is typically anchored to the place or thing. The majority of haunts are little more than a kind of etheric recording and aren't interactive. . . things don't move about, you can't speak with the spirit, etc. Interactive or "Intelligent" Haunts are very rare and similarly, rarely violent so long as you give them their space and treat them kindly. In the instances of aggressive entities there can be some very marked danger, especially if you attempt to exorcise it. That does not mean that you can't take steps to protect your family and home, you certainly can and based on how the entity reacts, you'll know if or not further steps are required.
I'm more than willing to give you some feedback if you're willing to share a bit more about the situation you're facing. Understand that I come form a strange position; I've very much a skeptic but at the same time a believer -- I've seen and experienced far too many things that can't be explained away but at the same time, I know for a fact that more than 90% of what folks encounter have a valid, down to earth explanation.
