We must already know that the end of the month are highly requested dates (end of lease) and the months of June / July are the most dense months in terms of international moving.
It is therefore recommended to start to contact a mover at least 1 month before in order to receive a full quote (3 to 5 days on average depending on the destination), to be able to choose among the quotes received, to have possibility to choose the most suitable date and prepare all necessary documents.
