To Change the country iTunes store click on the flag at the bottom and click on the flag for your country.
After that go buy Apple iTunes Gift Cards from eBay for the relevant country. Then click redeem on that country's store, enter code then set up account using separate email address from the US one (assuming you currently using iTunes with a US account)
Quick Guide on Vouchers:
Step 1 - Purchase a voucher.
Step 2 - Go into the Country of choice store.
Step 3 - Go to "Redeem Voucher" at the bottom of the page. iTunes will then ask you to register or log in, so you will need to register as a new user.
Step 4 - Register as a new user. To do this you need a Country of choice physical address. You can just select a real address at random from any internet directory, such as www.yellowpages.com for the Country of choice. The address is not verified by iTunes since you are only redeeming a Voucher.
Step 5 - Redeem your voucher and go shopping!
