Eeeeerm, I can help (as in order, pack and send you *small* things), but I'm already obligated to the Nismo GT-R model car crew...
I've ordered from Impul, Uras, Kazama, East Bear etc before, and although I ordered in Japanese, those guys weren't put off by sending internationally...? Send them an e-mail (try Impul first) and if the order can be sent via UPS, I don't see why you can't sort it out without help from your relatives.
