Before starting think about your budget and determine which activities you can perform yourself and which you are willing to subcontract to a moving company.
Also define which goods need to be moved, the volume of your household goods (in m3) is an important cost- driver. The moving company can execute a survey assessing the volume and particularities of your removal.
Please be aware that damages need to be avoided and proper packing is essential. Of course it is highly advisable to apply for an insurance, but inadequately packed items will not be covered. In other words consider to hire a moving company / packing specialist for packing.
