Self moving companies are often referred to it as "U-load We-drive". As the name imply, when you hire a self moving company, you do all the packing, loading, and unloading yourself, but you leave the hard part of driving the truck to a professional driver.
The process of self moving is very simple: the company drops a number of crates in front of your house, you load your belongings and furniture inside, lock the crates up, and the company comes to pick them up. Once you have arrived at your new home you call them up, they bring the crates and drop them in front of your new house.
