I think a fulfillment center will be more suitable for you. I am a shopify owner too, we have a lots of orders, but running a logistics department is too expensive.
And then I found my logistics partner right now, their quotation isn't the cheapest but the quanlity is the best.
My consumer mostly base on US, and they can delivery each item within 7 working days even I don't need a click.
For example, a 0.5kg item, total price of it at average is $10USD.

This is an accepted solution.
