International Movers to Belgium

Hello. We are international diplomats moving to Brussels in March of 2013 due to relocation orders. We want to know how much it will cost to move our furniture from Madrid (Spain) to Brussels and are looking for international movers to Belgium. We have 1 double bed, a dresser, small children’s bed, a wooden cabinet and 5 suitcases, a kitchen table, small dining room table and 4 chairs, living room glass cabinet and a sofa, piano and 3 bookshelves, 2 computers with flat screens, 2 paintings, 2 computer desks and 2 chairs, 1 cabinet, 2 small bookshelves, books etc. We need these items to be packed in Spain and unpacked in our apartment in Brussels. The piano will be sent in a separate box? What will it cost to insure its transport? Do you have the possibility to store items in Brussels? How long will the move take? Do you move on weekends also? Please send us the information as soon as possible. Relacation costs will be reembursed so would it be posssible to make an official proposal? Regards.
