I am still trying to get answers from my shipping company on if they have to pack everything themselves or not. He did tell me when I first talked to him that we could put things like books into boxes ourselves, we just cannot seal them, that they would do that so that they can make sure that there is no "illegal" stuff in there, and so that they can make the list for customs and such. I am still trying to figure out the technical end for the insurance as we are working on doing our valued inventory list for insurance purposes.
As far as space for the container. We are in a 3 BR townhouse, and are NOT taking most of our furniture with us. The only furniture we are taking are a couple small coffee tables, a computer desk, 2 wardrobe armoire things, a dresser, 2 nightstand tables and a few bookcases. Other than that we are just taking our usual everyday things like DVD's, computer, clothing, toys and such. We had a survey done by a company and they estimated that it would be about 4000lbs (things are charged by the weight) They said it would easily fit in a 20ft container, but like I said, we aren't taking all of our furniture (no couches, or dining room furniture, no TV's or kitchen appliances.) Hope this helps.
