You just need to make sure that you hire the right company because there are a lot of companies out there who will only cause you more grief than you already have. Before choosing a company, there are things that you need to consider so that you can protect yourself and your belongings.
The movers will only do so much as you tell them to and these services will be reflected in their bill. Some just ask the moving company to transport the belongings that they have already packed themselves. Sometimes also, if the move is cross country, people will rent a large truck and employ a crew to pack their goods and load the truck. These people will then drive the truck to their new location and there hire a new team of movers there who will unload and unpack their stuff. And there are, of course, those who would ask a moving company to do everything for them, from packing everything, to loading, moving, and unloading at the destination.
