Moving is a huge life event. It is stressful and often very overwhelming for individuals and families alike.
So, if you can afford it, there are organizations out there that can take some of that stress off of your shoulders by doing some of the "heavy lifting" for you.
Specifically, they will contact the movers, get estimates, assist in dispute resolution, setup contracts and organize whatever additional services you need.
Because of the volume business that they potentially bring to moving companies, they can often negotiate better discounts for you than the carrier might normally offer.
Though move consultant's services are usually paid for by commisions from the Moving Company - meaing that you won't get a bill from them, their cost is ultimately built into the cost of your move - so weigh your options carefully before handing over all control of your move to a consultant.
