Off the top of my head, that would be a form of 'dropshipping'.
You and your family agree (contract) that you will find the customer and handle the payment, and they will package and ship directly.
The most important thing is Shipping.
The Location on the Listing is the location of the item-- not your location.
This allows the customer to decide if she will wait a little longer and perhaps pay duty and sales tax on her doorstep when the item arrives from Asia.
Your shipping cost is not a factor for your customer. Of course it is important to you.
There is also the question of trust. Some customers are suspicious of goods shipped directly from overseas and would prefer to purchase from a Canadian source-- even if the item itself is identical.Even if the "Canadian " item is more expensive.
It is often less expensive to ship from overseas to a specific Canadian address than it would be for the seller to import a quantity and ship within Canada and hope to sell them all.
This might be useful.
