General Question

We are building a new and was wondering if anyone knew where we would start as far as listing items that could be drop shipped or fulfilled by the companies that carry the products? We are gonna sell lots of things on our own that we have but would like to sorta set up like, and I know that has a huge warehouse that they keep and store products themselves. That where we would like to be in the future but for now we would like to just list certain items for sale and then send the orders to the seller that is carrying the items for them to ship. I was thinking that would be a good starter, but don’t just want links. We would like to also have product descriptions and pictures to go along it all. any ideas are greatly appreciated. John
