dropsheet / dustsheet

I am wanting to purchase a container full of sheets from china. I have been quoted from the factory at their end F.O.B. Tianjin China. Basically do you provide a container at that end with an agent to check the goods going in the container. Then ship it back to me in Leicester. How does it work, as this is the first time i have done this. Also have you an idea of cost of a 40' container with a weight of approximateley 24,300kg. Regards Neil curley
