Hi, and welcome to the community...glad to hear that you like it!
I would suggest taking a look at a mail/parcel forwarding company based in the US. That would give you a US postal address, then allowing you to purchase from any US supplier and have the products shipped to you.
You could discuss options with the company about having them redirect the packages to other addresses as well, giving you the freedom to sell anywhere without the added shipping of having to come to you first.
Not sure if anyone actually provides that type of service, but I think it would be well worth while taking a close look at the options open to you through those avenues.
Cheers
