I haven't dealt much with companies that will ship you a tree........but my main concern would be that the tree would arrive damaged due to transportation. If this were to happen, you would be dealing with a further stressed tree from the beginning. And if you are wanting to harvest apples relatively quickly, as in the next few years (depending on the size of tree), the more you can help a tree by alleviating stress, the better and sooner you will be able to enjoy the fruit. Therefore, I would suggest trying to find your desired tree at a local nursery........or perhaps contacting a local arborist that may be able to sell you one or point you in the right direction.
