I have many crates of items that would be perfect for sale in places such in africa, who can i go through? -

I assume you mean second hand goods == I suggest you donate everything to a Charity (your shipping costs will exceed anything people in 3rd world can afford to pay)

There is a website that people in South Africa (still Africa) go on to sell such things. It s called gumtree. Just type it in Google. It s similiar to a classified ad.
