You can't do it if you already have bids.
If you have no bids and the option isn't there thenit means you don't qualify for international postage. All I can think of is that you don't have a verified paypal account.
You can permit a particular person to bid.
If they win then you can try sending a revised invoice, but there is a very good chance that they won't be able to pay via ebay. In which case use the request money tab in Paypal to send an invoice. Make sure you include a note of the item number.
